One consideration is that if syslogd is not running as root,
it will no longer be able to write to a filesystem which is
already "full".
On systems where non-root users can write to the filesystem
containing /var/log (and are not limited by quotas) this would
allow non-root users to disable logging, which would probably
be a Bad Thing.
