+\fBChrootDir\fR
+A directory to chroot in when everything is initialized. It doesn't need
+to be populated if ngIRCd is compiled as a static binary. By default ngIRCd
+won't use the chroot() feature.

+\fBPidFile\fR
+This tells ngIRCd to write its current process ID to a file. Note that the
+pidfile is written AFTER chroot and switching the user ID, i. e. the
+directory the pidfile resides in must be writeable by the ngIRCd user and
+exist in the chroot directory (if configured, see above).
