[SOLVED] unable to generate new initcpio's

27 October 2021, 20:03:54

So I precompiled `linux-mainline` including all docs and headers on a separate machine I have running Artix OpenRC, and then uploaded that to a [GitLab repo](https://gitlab.com/SimPilotAdamT/SimPilotAdamT-Arch-Repo) to install it onto my laptop (also running Artix OpenRC). Now, every time I try to make use `mkinitcpio` to allow my system to boot, it fails on my `lvm2` and `encrypt` hooks (I need those as my install is encrypted with luks 2) with the error `/usr/lib/initcpio/functions: line 196: add_udev_rule: command not found`. Any ideas?

My initcpio hooks are `base udev autodetect keyboard keymap modconf block lvm2 encrypt filesystems fsck`. I have the latest versions of `lvm2` and `cryptsetup` installed.

NOTE: `mkinitcpio` fails to work properly on all kernels I have, not just `linux-mainline`. I am having issues with `linux-zen`, `linux`, and `linux-xanmod`.

EDIT: just realised markdown doesn't work here lul

You could try installing eudev-git from the AUR, it might fix this if it was a udev problem, this has a very small risk of creating an unbootable system, in which case you might need to revert from a chroot, but it's probably going to be fine especially at this precise moment, there have been no commits since the new stable release just over a week ago.
(But I don't really know where the add_udev_rule is supposed to come from, that line just says:

Code: [Select]

    for _ in "${@:2}"; do
        "$1" "$_" || (( $# > 255 ? r=1 : ++r ))

so it is constructed as required at runtime)

No, forget eudev-git, actually that add_udev_rule appears here:
/usr/lib/initcpio/install/sd-vconsole
41: add_udev_rule 90-vconsole.rules
but nowhere else... unlike the functions called on the lines above, which appear in the functions file. So I guess your best chance of a quick fix is either add the missing add_udev_rule function to /usr/lib/initcpio/functions by copying it out of some older / newer version of mkinitcpio or delete / comment out the line referencing it in sd-vconsole and hope it works... make sure to copy /boot first because mkinitcpio overwrites the image files in there if you did try something, because working wrong could be worse than not working at all.

1) can confirm eudev-git was not the issue.....
2) deleting that line still produces that error... Maybe it's also somewhere else?

https://bbs.archlinux.org/viewtopic.php?id=183045
https://bugs.archlinux.org/task/60937
The answer there seems to be:
"The systemd hook was not included before the sd-vconsole hook."
But that doesn't sound too encouraging on a non-systemd distro!
Downloading the mkinitcpio repo, $ git grep 'add_udev_rule' $(git rev-list --all) seems to say that line has been there since 2016 and not anywhere else.
It might be worthwhile opening an issue here, unless anyone else here can come up with some better suggestions:

Since it hinders ability to use the distro looks like I'll have to....

Two solutions.
The first is to roll back cryptsetup one version back (cryptsetup 2.4.1-1 from cryptsetup 2.4.1-3)
The second is to fix install hook (/usr/lib/initcpio/install/encrypt).

Code: [Select]

    add_binary 'cryptsetup'

    map add_udev_rule \
        '10-dm.rules' \
        '13-dm-disk.rules' \
        '95-dm-notify.rules' \
        '/usr/lib/initcpio/udev/11-dm-initramfs.rules'

    # cryptsetup calls pthread_create(), which dlopen()s libgcc_s.so.1
    add_binary '/usr/lib/libgcc_s.so.1'

    add_runscript

Code: [Select]

add_binary "cryptsetup"
    add_binary "dmsetup"
    add_file "/usr/lib/udev/rules.d/10-dm.rules"
    add_file "/usr/lib/udev/rules.d/13-dm-disk.rules"
    add_file "/usr/lib/udev/rules.d/95-dm-notify.rules"
    add_file "/usr/lib/initcpio/udev/11-dm-initramfs.rules" "/usr/lib/udev/rules.d/11-dm-initramfs.rules"

    # cryptsetup calls pthread_create(), which dlopen()s libgcc_s.so.1
    add_binary "/usr/lib/libgcc_s.so.1"

    add_runscript

After fixing the hook, create a new initramfs (mkinitcpio -p yourkernel).
Unfortunately, I have no time to create commits, I hope it will be done by someone who has time and the developers will fix the cryptsetup package in their repository.

Brilliant answer, thanks! The only other thing I could think of was switch to dracut and see if that helped

That file is not a part of cryptsetup upstream, it's a script included with the Arch package. It's been copied across to the latest Artix version:
https://gitea.artixlinux.org/packagesC/cryptsetup/src/branch/master/x86_64
At this precise moment the problem version is still in the 'testing' dir at that url, later it will be merged into 'core' and the 'testing' entry will disappear until some new version joins the queue. No need to worry about PR's there as only Artoo and friends have the keys to that repo.
Actually I suspect that missing add_udev_rule could cause other problems from it being referenced elsewhere. The function comes from here:
https://github.com/archlinux/svntogit-packages/blob/packages/systemd/trunk/initcpio-install-udev
But you see there's already an unmerged pr to include it in mkinitcpio which might result in an upstream fix:
https://github.com/archlinux/mkinitcpio/pull/54
Another option could be to add that pr (if it fixes the issue) as an Artix patch.

Noted, cryptsetup and lvm2 won't move stable until fixed, probably tonight.

Should be fixed with eudev-249.5-2 in gremlins.
I opted to wait for arch including the function upstream mkinitcpio, which then needs an artix patch anyway.

Atm, eudev initcpio has the function.

Closing this topic as the issue as been resolved.

This indeed was what fixed it.

Note to anyone of the future having the same error message: this thread will be a dead end for you as this was an issue with the actual eudev package in the Artix repo's, not something that could be fixed using a few commands.
