/lib/systemd is currently hard-coded in samba's d/rules (and repeated
in multiple places).  It's easy to fix, but.

The same samba package is being built on multiple distributions and
releases, including ubuntu focal and jammy, debian bullseye and buster, -
I provide sort of backports for these releases and this service has
become quite popular.  The suggested

   pkg-config --variable=systemdsystemunitdir systemd

does not work on bullseye already.

What's an alternative way to determine if we should use /lib or /usr/lib
which works in older releases too - for systemd and for system libs like
libnss*?

Thanks,
