When a package contains a directory in one of the systemd directories
(like flatpak does), it is symlinked into the *-units derivation.
Then later, the derivation will try to create the directory, which
will fail:
mkdir: cannot create directory '/nix/store/…-user-units/dbus.service.d': File exists
builder for '/nix/store/…-user-units.drv' failed with exit code 1
Closes: #33233
We currently only allow upstream's default of "reboot.target" due to the
way the symlinks are initialized. I made this configurable similar to the
default unit.
During the refactor of the networkd stuff in f8dbe5f, a lot of the
options are now needed by systemd.nix as well as networkd.nix but
weren't moved by that commit as well.
For now, this fixes all networkd VM tests except for the macvlan one and
thus it should fix#7505 for at least DHCP-based configuration.
