Hi,
To help with flashing the onboard eMMC of a 100000 boards I'm using
systemd-nspawn to run package postinstall scripts that generate UUIDs and some
other things and it's working great for that! Every board now has a unique
value in /etc/machine-id instead it being empty and systemd randomizing it on
startup.
What doesn't work however is something like this:
systemd-nspawn -D ${PART2MOUNT} /usr/bin/timedatectl set-timezone
Europe/Paris
or this:
systemd-nspawn -D ${PART2MOUNT} /usr/bin/hostnamectl set-hostname
BeagleBoneBlack
I know I can run the lowlevel 'ln -sf <zoneinfo> /etc/timezone' or echo the
name into /etc/hostname, but I'd like to use the *ctl commands because they
work and have error handling built-in.
it looks like I would need -b to get the *ctl commands to work, but -b doesn't
support running single commands and exiting.
My goal is to be able to drop in a rootfs tarball and change timezone and
hostname settings in a config file for the flasher script and avoid generating
N different tarballs. For use in the office lab I use something like [1] to
generate the hostnames based on board revision and serial number.
So, is there a way to *ctl command using systemd-nspawn in a rootfs that wasn't
specially prepared (e.g. helper units/targets) for that?
regards,
Koen
