dracut kernel hook appears to have issues

[CameronNemo]

System

• xuname:
  output of xuname (part of xtools)
• package: dracut-051_2

Expected behavior

dracut kernel hook does not send a bunch of info on stderr

Actual behavior

Seeing this on the output, even though dracut seems to make the initramfs alright:

Executing post-install kernel hook: 20-dracut ...
dracut-install: No SOURCE argument given
Usage: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... -a SOURCE...
or: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... SOURCE DEST
or: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... -m KERNELMODULE [KERNELMODULE …]

Install SOURCE (from rootfs or SYSROOTDIR) to DEST in DESTROOTDIR with all needed dependencies.

  KERNELMODULE can have the format:
     <absolute path> with a leading /
     =<kernel subdir>[/<kernel subdir>…] like '=drivers/hid'
     <module name>

  -D --destrootdir  Install all files to DESTROOTDIR as the root
  -r --sysrootdir   Install all files from SYSROOTDIR
  -a --all          Install all SOURCE arguments to DESTROOTDIR
  -o --optional     If SOURCE does not exist, do not fail
  -d --dir          SOURCE is a directory
  -l --ldd          Also install shebang executables and libraries
  -L --logdir <DIR> Log files, which were installed from the host to <DIR>
  -R --resolvelazy  Only install shebang executables and libraries
                     for all SOURCE files
  -H --hostonly     Mark all SOURCE files as hostonly

  -f --fips         Also install all '.SOURCE.hmac' files

  --module,-m       Install kernel modules, instead of files
  --kerneldir       Specify the kernel module directory
  --firmwaredirs    Specify the firmware directory search path with : separation
  --silent          Don't display error messages for kernel module install
  --modalias        Only generate module list from /sys/devices modalias list
  -o --optional     If kernel module does not exist, do not fail
  -p --mod-filter-path      Filter kernel modules by path regexp
  -P --mod-filter-nopath    Exclude kernel modules by path regexp
  -s --mod-filter-symbol    Filter kernel modules by symbol regexp
  -S --mod-filter-nosymbol  Exclude kernel modules by symbol regexp
  -N --mod-filter-noname    Exclude kernel modules by name regexp

  -v --verbose      Show more output
     --debug        Show debug output
     --version      Show package version
  -h --help         Show this help

Steps to reproduce the behavior

No idea really. Happens on some upgrades, but not others. Most recently linux5.10 update 5.10.24_1 5.10.25_1 87MB. Was wondering if anyone else has experienced this.

dracut-install: No SOURCE argument given

I think I have seen comments about this. Sounds like an upstream issue, if it's calling the program with missing arguments, but I haven't looked at the code yet.

Would you mind run dracut manually in verbose mode to see what wrong?

[sgn]

Can you check those files existed?

• /var/lib/dbus

[CameronNemo]

I have tried running dracut manually and cannot reproduce the message. Only when run by xbps.

Hm, I could only suggest remove -q from 20-dracut kernel hooks, and maybe replace it with -v and see if any other errors.

[rafaelgoncalves]

Same error on my void box, this after add hostonly configuration on dracut.conf.d and like @ericonr said, this looks like a upstream issue:
dracutdevs/dracut#1096

[ahesford]

This should be fixed in current versions of dracut. Please comment if not.
