Subject: [PATCH] mountd: Initialize logging early.

Reading the config file can generate log messages,
so we should initialize logging before reading the
config file.

If any log message are generated, syslog will leave
a file descriptor open (a socket), so calling
closeall(3) after this can cause problem.
Before this we initialize login we don't know if
Foreground (-F) has been selected, so closeall()
cannot be conditional on that.

closeall() isn't needed - daemon are almost always run
from a management daemon like systemd, and they are given
a clean environment.  It is really best if they just take
what they are given.

So remove the closeall() call.
