From my perspective this is a simplified implementation, service files have very simple and well documented behavior, any complication I see seems to be inherent to the problem space and existed before systemd came on the scene, so it’s not created by systemd. A simple service example would be rsyslogd.service which just reads /etc/sysconfig/rsyslogd and runs /sbin/rsyslogd -n $SYSLOGD_OPTIONS a more complicated example would be mounting NFS filesystems, which has a bunch of dependancies on RPC port mapper services like idmap or gssapi a special filesystem in /var/lib/nfs etc. Neil Brown wrote a series of articles for LWN on replacing the shell scripts in nfs-utils with systemd unit files for SuSE. https://lwn.net/Articles/584175/ So simple things are trivial, more complicated things are possible and the options are there in the config file if you want to use them but you aren’t forced to. — Mark Tinberg, System Administrator Division of Information Technology - Network Services University of Wisconsin - Madison mtinberg at wisc.edu
