At this point, I would say stick with systemd. It _does_ still have minor teething problems, but they are really mostly corner-cases. Occasionally migration incompatibilities appear where systemd no longer supports what one was used to in sysvinit (see for instance Carlos' spamd issue re inline comments).
How would you do something like the attached in systemd?

Note -- to make effective use of # this client, it is necessary to allow incoming and # outgoing traffic through a firewall. # Only 1 port needs to be open and this can be defined # statically -- so you can manually add rules to your # firewall. The daemon will use upnp to talk to a # compliant firewall to ask it to open a port for it, # allowing for port randomization on startup, if that # is desired. Software upnp programs, like 'linux-igd' # are freely available by searching on the web, will # function as a upnp gateway and will manage connections # through a linux or other firewall. ### END INIT INFO # ## support code & functions Id="$(type -p id)" Sed="$(type -p sed)" Sudo="$(type -p sudo)" use_group_access=1 if ((use_group_access)); then unset Groups typeset -Ax Groups function _idparse { # parse output of id: # uid=##(name) gid=##(name) groups=##(name)[,##(name)]... # Note, names may be 'absent' (in which case there are no parens). # grouplist is *comma* separated! -- but only on output of 'id'; # I don't "idnames" can start with a number...
