#34616 — Re: forking and avoiding zombies!

Ah sure that makes sense!

But actually why do I need to move away from the current directory of
the parent process?
In my case it's actually useful to be in the same directory, so maybe
I can skip that part,
or otherwise I need another chdir after..

It's not required, it's just "best practice".

Often, the current directory is simply whichever directory it happened to
inherit from the shell which spawned it. So long as that directory
continues to be used as the daemon's current directory, the filesystem
on which it resides cannot be unmounted. So daemons normally change to the
root directory (or to some other directory, e.g. one which they actually
need to use) in order to "release" the directory from which they were
initially started.
