Btrfs and nspawn
by Pocket 28 Sep '25

28 Sep '25

I have a system that uses btrfs for the root filesystem. I created a subvolume root which becomes the root filesystem on boot up, ie it bootds to the root subvolume. I now want to add some "containers" to that machine, for example DNS. When set up with bind and started with machinectl provides DNS for the network. Is it possible to use a snapshot for the root subvolume for nspawn containers? I have seen that one can use the --template option but it appears to be a newly created container every time. Thsat won't work as I would lose the bind setup. I need something that is not volatile in which I can install bind an configure it without having to do that every time the container is shutdown and the restarted. Also if I can use the root subvolume as a template will the subsequent containers be updated when I use pacman -Syu to update the root subvolume? -- Hindi madali ang maging ako

The whole point of a container is, that it can be run and > updated independently of the host. Or is there anything I missed? I am doing this already on a host that uses ext4 for the filesystem and I wish to change that to btrfs. By using a container (systemd-nspawn) it allows me to keep the service separate from the host system. I then can copy that to move the container to another host without trouble. I am doing this on a single host that has containers for DNS, Nginx and dovecot/opensmtpd. I want to snapshot the "root" subvolume as the starting point for the container. If I understand the process the I won't have to "install" the "rootsystem" in each container and they will share those files. The only differences will be whatever changes need to be made for each container saving a bunch of SDD space. When setting up the "subvolumes/containers" for each service if I use the --template option it appears to do that but it is voltile as it will setup a new subvolume each time that will a "copy" of the the root subvolume, without bind and settings. I originally though I could do this by snapshotting the "root" subvolume and then use that for the systemd-nspawn container starting it with machinectl upon system boot. I have not tried that. I am asking if anyone here has done something like this.

/boot full
by Brian Keck 26 Sep '25

26 Sep '25

Last time (24 Aug) I updated arch on my laptop, /boot filled up. [1] There was a message saying that the build of /boot/initramfs-linux-fallback.img failed [1] [2] seems to say to adjust /etc/mkinitcpio.conf by dropping kms from HOOKS & adding i915 to MODULES. But this makes me nervous, so I'm asking here. Laptop has only Intel graphics [3], & lsmod shows both i915 & xe. I'm using both X11 & Wayland. Is the above advice good? Should I add xe to MODULES as well?

Sway Crashes After Recent Updates
by Radosław Kintzi 24 Sep '25

24 Sep '25

Not sure if this is the righ forum to report this kind of problems, but after this morning's `pacman -Syu`, I began to observe that Sway crashes each time DPMS is forced off, for example after `swaymsg "output * dpms off"`. Downgrading wlroots0.19 (0.19.1-2 => 0.19.0-5) and libdisplay-info (0.3.0-1 => 0.2.0-2) (and mpv) "fixes" the problem. Small excerpt from the system journal: wrz 24 10:07:01 ganges sway[1030]: sway: backend/drm/drm.c:1453: realloc_crtcs: Assertion `conn->crtc != NULL' failed. wrz 24 10:07:01 ganges systemd-coredump[1262]: Process 1030 (sway) of user 1000 terminated abnormally with signal 6/ABRT, proc> wrz 24 10:07:01 ganges systemd[1]: Created slice Slice /system/systemd-coredump. wrz 24 10:07:01 ganges systemd[1]: Started Process Core Dump (PID 1262/UID 0). wrz 24 10:07:01 ganges systemd-coredump[1263]: [🡕] Process 1030 (sway) of user 1000 dumped core.

failing to preform offline installation
by daggs 20 Sep '25

20 Sep '25

Greetings, I have a server that serves as router via vm, I'm attempting to install arch offline. here is what I did, I've created a json config to load using archinstall to preform the actual install. after selecting all the pkgs needed, I've extracted them from the json file and ran this: pacman -Syw --cachedir /mnt/repos/cache --dbpath /mnt/repos/db ..... now I have all the pkgs I need, next I've entered /mnt/repos/cache and ran this: repo-add ./custom.db.tar.zst ./*[^sig] according to the docs, I have local repo if I understand correctly. next I've booted the system in question and updated /etc/pacman.conf and added this: [custom] SigLevel = PackageRequired Server = file:///mnt/repos/cache I ran archinstall, got this: Fetching Arch Linux package database... Failed to sync Arch Linux package database. Most likely due to a missing network connection or DNS issue. Run archinstall --debug and check /var/log/archinstall/install.log for details. how can I instruct archinstall to use my local repo? Thanks.

How to stop email notifications from gitlab.archlinux.org
by Uģis Ģērmanis 19 Sep '25

19 Sep '25

Hello, There was a time I wanted all gitlab activity sent to my email, so i set Preferences => Notifications => Global notification level => Custom (to the activities I was interested) Now times have changed and I no longer have to the time to catch up with thousands of emails a week. So i tried setting the activity level to "Participate" which should only notify about things I'm involved in somehow, like issues I've commented on or things I've explicitly set to be notified about. But I still receive emails about issues created mostly by Bumpbuddy (and some others). Like hundred emails a day. Also ticking and unticking "Receive notifications about your own activity' doesn't seem to change anything either. I also tried to set the global notification level to "Disabled" which should kill all emails as it says but even that has no effect either. If I do a search on issues " Subscribed = Explicitly subscribed", I only get 1 closed issue. So I believe something is broken, because I haven't explicitly subscribed to anything that much, so the global setting shouldn't be bypassed. ugjka

Unable to access Arch Wiki
by KevinCrrl 12 Sep '25

12 Sep '25

Hello everyone, Since yesterday, I've been having trouble accessing the Arch Wiki from my network. My browser tells me the site is taking too long to respond. I've already tried things like changing DNS and restarting my router (which still gave me the same IP address I had). I know there were recent DDoS attacks against other Arch sites like the AUR. However, I've checked the Wiki status [1] and everything seems normal. I've also tried using tools to change the IP address, and I can access it. I've confirmed there are recent edits, which tells me it's not a global issue. My concern is that they've blocked me—not my username, but my IP address. I tend to be active reading and editing on the Wiki. Could someone confirm whether IP-based blocks are currently in place, and if so, how can I request to be unblocked? Thanks to anyone who can help.

Trouble registering with Arch ARM forum
by kelson+arch＠kvibber.com 05 Sep '25

05 Sep '25

I've been trying to register for the Arch Linux ARM forums off and on for a few weeks. Before the DDOS attacks, I was able to get through the registration form, but never received any confirmation emails (yes, I looked in junk mail). When I tried again this week, figuring I'd try using an address from a more well-known provider, I found the captcha no longer loads, so I can't even get through the form. The JS console reports `ERR_CERT_COMMON_NAME_INVALID` on trying to load `cap.js` from the third-party keycaptcha domain, which seems a likely culprit. Is there anyone here connected with the ARM forum who could look into fixing the captcha or the missing emails? I didn't get any response on IRC, or from the one email address listed on the Arch ARM website (which isn't for the forums, I know, but I figured it was worth a shot), and the main Arch forum admins told me to ask the ARM forum admins, despite the fact that the forum doesn't list any admin contact info if you aren't logged in. Which I can't be, because the problem is that I can't get through the registration form. -- Kelson Vibber KVibber.com

cp from internal SSD via USB 3 to external HDD is very slow
by Ralf Mardorf 26 Aug '25

26 Aug '25

Hi, I am copying from an internal SATA SSD via USB 3 to an external SATA WD Blue, a 3.5" CMR HDD. The first part “cp -ai /mnt/winos7/” (see [*1]) took about 70 minutes for 188 GiB, almost all files are quite small. The second part “cp -ai /mnt/winos10/” (see [*1]) should copy about 100 GiB small files + about 740 GiB for a single vbox vdi file. The about 100 GiB small files were copied and about 310 GiB of the vdi file were also already copied, at 03:30, so for about 410 GiB it took about 9 hours. I think this is taking far too long. Does anyone have an idea? FWIW ^Z was an oversight. I meant to press Ctrl+Alt+T to open a terminal tab, and apparently pressed Ctrl+Z (German QWERTY keyboard).
