Not quite. While you can use drop-in snippets to amend orderings/depends, it's (unfortunately) not possible to override Wants=,Before= etc. With insserv overrides you can apparently *replace* the LSB header of an SysV init script. >> You couldn't override init scripts that way - if you wanted to do that, >> you'd have to replace them completely.

To be fair, there is https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=759001 We never raised that upstream though. >> Note that on servers running Debian I've used /etc/insserv/overrides >> countless times over the past years, so maybe chkconfig.d wasn't >> something that was widely popularized, but insserv/overrides definitely >> was. > > Again given that on DEbian we don't even have hookup to > insserv/update-rcd, I kinda wonder if it would be appropriate to > support this facet of it, without supporting the actual core bit. > > I also believ that "systemctl edit" is a much nicer interface for all > of this, and it works on both sysv scripts and unit files... Agreed, systemctl edit is much nicer. Unfortunately, as said above, drop-ins can *not* be used to override all aspects of a native unit file. So it's not (yet) a complete replacement for insserv overrides. If it would be possible to unset Wants= or After=, just like other service properties, then things would be different. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
