Hi,
A few questions regarding usage of systemd+udev in initramfs. Before all,
this is what I want to achieve (to prevent XY-problems): working
emergency.service in initramfs.
The questions are a bit Arch-specific and possibly lame, but well...
- is /etc/passwd still[1] needed in initramfs due to libdbus1?
Hmm, good question.
I think for the simpler cases /etc/passwd could be empty now. However,
as soon as networkd is thrown into the mix we really want the
systemd-network user around, so that networkd can drop privs, which
it really should do a network-facing daemon that it is.
- how to pass '--resolve-names=never' to udevd in initramfs, will it work this
way and will it allow to exclude /etc/group[2] from initramfs?
You should be able to pass it in the systemd-udevd.service unit file
you ship in the unit file. I think doing this should be OK, but I
figure you have to try. That all said, due to the systemd-network
user I am not convinced that a /etc/passwd-less initrd is really
useful for more than the simplest cases.
- is it possible to use 'sulogin -e' instead of 'sulogin'[3]
security-wise?
Sure, just override the upstream unit files in question. That said, I
am a bit afraid of making this change upstream...
