[Nfdump-discuss] change user vs permission to create /var/run/nfcapd.pid

[Scott B. <ss...@um...>]

Drop root privs happens before the PID file is created which is a hassle
since it isn't always trivial to make a persistent subdirectory in /var/run.

Wondering if the code: SetPriv(userid, groupid);
in nfcapd.c, nfpcapd.c, and sfcapd.c
could be moved after the PID file is created.  It doesn't seem as though
this is problematic (works great for me in nfcapd!) since daemonize() is
the only code that seemed likely to do anything worrisome...and all that
does is fork(), setsid(), and fork().

Thanks, Scott
