That's interesting. libnss-systemd ships a valid postrm script that's
supposed to do just that - removing "systemd" entries from
nsswitch.conf ($module=systemd, $file=/etc/nsswitch.conf):
# we must remove possible [foo=bar] options as well
sed -i -r "/(passwd|group):/
s/[[:space:]]+$module\b([[:space:]]*\[[^]]*\])*//" $file
But:
1) postrm script bails if it finds that libnss-systemd is still
installed, but for another architecture.
2) It invokes "sed", not "/bin/sed", and that's another possible reason
for such failure - locally installed /usr/local/bin/sed which does not
understand "-i" option or misinterprets that regexp.
I suggest you to file a bug against libnss-systemd. They use perl in
postinst already, they might use it in postrm as well.
