danuan | onefang / in single user mode while remounted to ro | 00:00 |
---|---|---|
danuan | and after dd of original /dev/sda to /dev/sdb | 00:00 |
danuan | drives are identical | 00:00 |
danuan | let see if it goes back to init 2 | 00:01 |
danuan | shit , when going to mount -remount,rw it revers back to whatever is in fstab for / | 00:02 |
danuan | so i err nevermind , it did not | 00:02 |
danuan | it seems to have worked, i might be mistaken , which is whye i will try this again , but so far , going single user , mount -o remount,ro , dd the system drive to another , then mount new drive over old / and remount to rw and init 2 seems to have worked | 00:04 |
danuan | cat /etc/mtab still shows old drive mounted ro , but new drive is overmounted rw | 00:05 |
danuan | my mistake , both were still mount rw , and was not able to umount original drive but second drive unmounted fine, so i guess original drive still was on top | 00:12 |
danuan | so even though df shows new drive mounted as / rw , it is not , trying to touch anything give readonly filesystem | 00:16 |
danuan | it seems there is switch_root for this procedure | 00:38 |
Xenguy | fsmithred: Where's the best spot to chat about refracta, here or elsewhere? | 01:27 |
fsmithred | here or offtopic is ok | 01:28 |
Xenguy | Cool... | 01:28 |
Xenguy | I'm assuming that it would take awhile to generate an ISO of a running system... | 01:29 |
Xenguy | I was thinking of trying to backup my existing system to an ISO on my new external drive (ED)... | 01:30 |
Xenguy | (I did end up reformatting the ED to EXT3 filesystem, which I think works much better with rsync) | 01:30 |
fsmithred | on my athlon X2 from 2005 it takes about 40 minutes. On the quad i7 it takes 10. | 01:31 |
Xenguy | That sounds surprisingly fast to me, interesting... | 01:31 |
golinux | Most all my drives are ext4 and I rsync to backup | 01:32 |
Xenguy | This laptop is my slowest system, and has an i3 processor, so perhaps a bit longer then. I will time it, just out of interest. | 01:32 |
fsmithred | rsync and mksquashfs run multi-threaded | 01:32 |
golinux | First backup takes a while. Updates go pretty fast | 01:32 |
fsmithred | the i7 has hyperthreading, so it acts like 8 cores | 01:32 |
Xenguy | The fastest laptop I have is i5 I think | 01:33 |
fsmithred | it won't take very long | 01:33 |
Xenguy | I'm thinking about getting another one this weekend, but it'll probably be an i5 also | 01:33 |
Xenguy | Good to hear, if I run into any questions, I'll hit you up if you're around. I've never tried refracta before. | 01:33 |
fsmithred | if you have a lot of data, you should exclude it and back it up a different way. Better to keep the iso smaller. | 01:34 |
Xenguy | I have run rsync on my data, so I'll see about excluding that part, if I can figure it out. | 01:34 |
fsmithred | you can go beyond 4GB, but that seems crazy. | 01:34 |
fsmithred | just add stuff to the excludes list. I believe you can even edit it from the gui program itself. | 01:35 |
Xenguy | Sounds good. Might not happen tonight now, but I'd prefer to do that before I initiate the upgrade to beowulf. | 01:36 |
fsmithred | yeah, Setup is in the first menu | 01:36 |
Xenguy | Perfect | 01:36 |
Xenguy | Did you code refracta yourself? | 01:37 |
fsmithred | mostly myself. | 01:37 |
fsmithred | the basic commands were worked out by meandean | 01:37 |
fsmithred | he had someone put it in a python script to guify it | 01:38 |
fsmithred | I converted it to bash and not long after was handed the whole project | 01:38 |
fsmithred | dzz helped with the coding | 01:38 |
Xenguy | Good on you, that's pretty impressive. | 01:38 |
fsmithred | in a few months, it'll be 10 years | 01:39 |
Xenguy | I had no idea it's been around for that long. I had thought it was fairly recent issue. | 01:40 |
fsmithred | and there used to be a forum and a community, so there was a lot of input from other people | 01:40 |
fsmithred | snapshot, installer, the live isos, refracta2usb (dzz's creation) | 01:40 |
fsmithred | so I've had a good opportunity to learn about feature creep and spaghetti code. | 01:41 |
Xenguy | hehe, I'll bet | 01:41 |
fsmithred | bottom right of the first screen is a Help button. I forgot that was there. | 01:48 |
Xenguy | thanks | 01:51 |
* Xenguy goes to rewatch The Trial of the Chicago Seven... | 01:52 | |
icemodding | hi ppl | 03:28 |
danuan | they will not respond until you ask a question, then everyone jumps in :) | 03:35 |
tuxd3v | icemodding, hi | 03:43 |
icemodding | wzup tuxd3v | 03:43 |
onefang | This is a support channel, not a chat general channel. | 03:44 |
icemodding | ok, sorry | 03:46 |
clort | reading up on ccache, it says it is 'not for multiple file compilation? what does that mean | 03:56 |
clort | i wouldn't mind smarter/faster recompiles of scummvm and other larger projects | 03:56 |
clort | but i see how this isn't trivial to do | 03:56 |
gnarface | clort: never used it, but the documentation says it's about "multiple source files in one go" which i would suspect is fairly common... | 05:09 |
gnarface | but it also just says unsupported so that isn't always a guarantee it won't work | 05:09 |
clort | ccache -s shows me stuff, with a hit rate and stuff | 05:10 |
gnarface | oh, so maybe it'll just ignore those parts of the build | 05:10 |
gnarface | and only cache stuff it can | 05:10 |
gnarface | got multiple machines handy? you could try distcc instead | 05:11 |
clort | yeah i have a bunch sitting here doing nothing. would be fun to have them working for me | 05:11 |
gnarface | i've heard that distcc can break parallel builds, but if you have enough machines then having distcc kinda obviates the need for parallel builds anyway | 05:12 |
clort | but over usb-networking, not wlan | 05:12 |
gnarface | that's fine, usb is faster actually | 05:12 |
gnarface | by wlan you mean wireless, right? | 05:12 |
clort | yes | 05:12 |
clort | i can get one d4 talking on usb0, but not two or more | 05:13 |
gnarface | usb2 should be anywhere from 3 to 40 times faster | 05:13 |
gnarface | depending on the type of wifi | 05:13 |
clort | i think i'll waste less time faffing by cross compiling on the khadas vim3 | 05:26 |
clort | ah it's important to prepend the /usr/lib/ccache to your $PATH | 05:29 |
clort | yup ccache is puppies and birthday cake, rebuild went from 15-16min to 39 seconds | 05:33 |
crashoverride | mz`: what's up with your uplink? | 15:02 |
GyrosGeier | hi | 15:45 |
GyrosGeier | is anyone working on an updated kernel in beowulf-security? | 15:46 |
gnarface | if there is one in debian that's not in devuan yet it's probably the build cluster that's working on it | 15:46 |
xinomilo | it's already there : https://pkginfo.devuan.org/stage/beowulf/beowulf-security/linux-image-amd64_4.19+105+deb10u7.html | 15:47 |
gnarface | afaik those packages shouldn't be changed but some of the related packages might | 15:47 |
gnarface | the mirrors might take some time to relay out | 15:47 |
GyrosGeier | ah okay | 15:47 |
GyrosGeier | so that'll happen | 15:47 |
* GyrosGeier moves maintenance window for the docker box to the evening | 15:47 | |
catch21 | hello. when I try to view the files in a different partition, all the files are executables, even PDFs. Meanwhile, the files on a flash drive are normal. The devices appear on the left hand side of Thunar. I click and they get mounted. | 15:52 |
catch21 | mount gives | 15:54 |
fsmithred | catch21, don't post a bunch of lines at once. | 15:55 |
fsmithred | use paste.debian.net | 15:55 |
catch21 | sorry | 15:56 |
gnarface | catch21: (also, that's usually expected behavior if you're copying files from windows) | 15:56 |
catch21 | it's normal? can't I make it behave like the flash drive? | 15:57 |
fsmithred | np, you didn't do anything. Maybe your post started with / and did not show up. I was just warning you about the security bot that might kick you out. | 15:57 |
gnarface | catch21: just use a different filesystem | 15:57 |
catch21 | so it goes with ntfs? | 15:57 |
catch21 | weird | 15:58 |
gnarface | catch21: fat32 doesn't support permissions, it's weird and unsafe that the default is rwxr-xr-x, and you can override it with a mount option but you can't make it support permissions | 15:58 |
fsmithred | yeah, I've seen windows make all kinds of stupid stuff executable | 15:58 |
gnarface | catch21: ntfs is the same situation, but if it's a sd card or usb flash i would have assumed fat32 | 15:58 |
gnarface | there are windows drivers for some linux filesystems if you need to trade files between the two though | 15:59 |
gnarface | not that i'd recommend it | 16:00 |
catch21 | it's all rwx for all, though for the ntfs partition | 16:00 |
catch21 | the usb drive has fmask=0022,dmask=0022 | 16:00 |
gnarface | the filesystem has to support the mount options | 16:00 |
gnarface | i don't know what ntfs supports | 16:01 |
gnarface | the man page should say | 16:01 |
catch21 | meanwhile, the ntfs partition has no mask thingie and the user_id=0 | 16:01 |
catch21 | is that the kernel? | 16:01 |
gnarface | the filesystems should have their own man pages | 16:01 |
gnarface | if not try the mount command for it | 16:02 |
catch21 | i even used su chmod and no changes | 16:02 |
catch21 | sudo i mean | 16:02 |
gnarface | hmmm, although... i see the mount.ntfs man page here says umask and dmask are supposed to be supported, at least for ntfs-3g | 16:03 |
gnarface | hmm, for general too | 16:03 |
gnarface | odd | 16:04 |
gnarface | i can't say i use it much, but i recall that it was marked experimental in the kernel for a long time, and write capabilities were disabled by default... i'm not sure that's not still the case, did you check for that? | 16:04 |
gnarface | if write protect was enabled at the kernel drier level, chmod wouldn't do anything | 16:07 |
gnarface | *driver level | 16:08 |
catch21 | sorry that's over my head | 16:08 |
fsmithred | I think ntfs-3g write was fixed a few years ago | 16:08 |
catch21 | just a regular user | 16:08 |
fsmithred | that's what I recall. I don't use it. | 16:09 |
gnarface | catch21: you're using beowulf, right? | 16:09 |
catch21 | ascii | 16:09 |
gnarface | hmm, that's a much older kernel | 16:09 |
gnarface | you should try a beowulf live image | 16:09 |
gnarface | see if it works, if so consider upgrading | 16:09 |
catch21 | i tried setting umask to 0022 with mount.ntfs-3g and there has been a change. | 16:18 |
gnarface | as a mount option? | 16:18 |
gnarface | well that's good | 16:18 |
gnarface | that's something anyway | 16:18 |
catch21 | at least the write permissions | 16:19 |
catch21 | thanks for the tip | 16:19 |
catch21 | yes as mount option | 16:19 |
gnarface | it would be best to just use a different filesystem really, but i know it's not always allowed | 16:19 |
catch21 | i have windows on another partition and I need to see my notes and stuff | 16:20 |
catch21 | from there | 16:20 |
wikan | hi | 18:01 |
wikan | did anyone try hurd kernel? | 18:01 |
n4dir | way back. and not on devuan. | 18:02 |
wikan | i wonder what would happen if I install it | 18:03 |
n4dir | as i never heard anyone say it would be possible to simply install a hurd kernel on a stock debian, i doubt that would work | 18:04 |
wikan | well dunno. I see a package | 18:04 |
wikan | but I use some functionality like luks | 18:05 |
mason | wikan: poke through things like https://wiki.debian.org/Debian_GNU/Hurd to get a notion of what's involved | 18:22 |
n4dir | getting it run command line only was do-able. Gui was the hard part, and i had to give up. iirc i did get a gui, but no mouse or keyboard. | 18:25 |
n4dir | kFreeBSD was pretty easy compared with hurd. You hardly recognized it you weren't running Linux kernel | 18:26 |
n4dir | but as said: back then, ages ago, all that might well have changed. | 18:26 |
wikan | i always try to install as tiny os as it is possible | 18:28 |
wikan | for workspace I like it is about 110MB | 18:28 |
wikan | maybe it is time to replace a kernel :) | 18:29 |
wikan | or... try freebsd on one machine | 18:29 |
wikan | i am a person for whom even kernel size may be important ;) | 18:30 |
* n4dir waits for the reasoning behind that approach ... | 18:35 | |
wikan | hobby | 18:38 |
n4dir | as good a reason as any other :-) | 18:41 |
brocashelm | is it just me, or is kernel 5.9 really screwy? | 19:15 |
brocashelm | 5.8 was working fine, but now newsboat takes forever to open an article (i use mpv as "browser") | 19:16 |
tuxd3v | mesa 20.3 will be huge with their OpenCL Clover Driver now in OpenCL v1.2 | 20:00 |
tuxd3v | it seems to ve already working well for nvidia cards.. | 20:00 |
tuxd3v | for AMD cards still lacks Image Support.. | 20:01 |
