dcron crashes without it, which is why [1] exists. The log says
`setpgid: Operation not permitted'. I have not investigated further.
The problem happens here:
https://github.com/dubiousjim/dcron/blob/master/main.c#L272
dcron assumes that it's not a session leader when run in the
foreground.
This is a programming error that should be reported and fixed; if
setpgid(0, 0) fails with EPERM, it just means that the process is
already a session leader, and the program should simply keep running
instead of exiting.
So, not a valid reason. ;)
As a workaround, you can avoid nosetsid by just running dcrond under
execline's 'trap', or a shell, or basically any program that will
just forward signals to it.
