Hi,
I have similar question (sorry for stealing this thread). I have package
that has 3 services (they somehow depend on each other). Based on
configuration in /etc/sysconfig/.. file it starts 2 or 3 services. This is
handled by init script, but I don't know how to do it in systemd service
file.
AFAIK:
a)
EnvironmentFile=...
ExecStart=[ -n "$DRIVER" ] && /start/driver/...
ExecStart=[ -n "$BACKEND" ] && /start/backend/...
ExecStart=[ -n "$MONITOR" ] && /start/monitor/...
won't work, because ExecStart must be path, not shell command
b)
ExecStart=/usr/libexec/%{name}/startifset "$DRIVER" /start/driver
ExecStart=/usr/libexec/%{name}/startifset "$BACKEND" /start/backend
ExecStart=/usr/libexec/%{name}/startifset "$MONITOR" /start/monitor
won't work, because there ExecStart can't be used more than once,
except with type=oneshot, which does not work here
c)
ExecStart=/usr/libexec/nut/startthemall
this is only workable solution I know (for now), but I don't know if it's the best one
d) split it to more service files and make dependency there
this would be incompatible change in configuration and hard to do, because
dependency can change with configuration
Is there a good solution for this?
Michal
