jail + mount_union problem

[Victor Polyakov]

We have a system with some jails. First jail's home directory is /data/jails/ref. Then, we are running script "crash" under root:   -----------   #! /usr/local/bin/bash   SRC="/data/jails/refDEST=/data/jails/$1 mkdir $DEST   mkdir $DEST/usr mount_union -b $SRC/usr $DEST/usr   mkdir $DEST/bin mount_union -b $SRC/bin $DEST/bin   mkdir $DEST/root mount_union -b $SRC/root $DEST/root   jail /data/jails/$1 jail$1 $2 /bin/csh /root/scripts/runjail   mount_union -b $SRC/usr $DEST/usr   mount_union -b $SRC/bin $DEST/bin   mount_union -b $SRC/root $DEST/root --------------   Originally, this script was designed to make a clone of the first jail. Contents of /root/scripts/runjail:   -------------   sshd /usr/local/apache/bin/apachectl start cd /usr/local/mysql bin/safe_mysqld --user=mysql & cron   -------------   After this, system hangs up. When trying to reboot with "boot -sv" we see:   ... ... trying /sbin/init...   and freebsd halts again. There is no way to boot up. Of course, fsck reports "no problem" and checksum of /sbin/init is correct. The only way to continue working is to run "upgrade" from the instalation CD.   We are using freebsd 4.5.   May be anybody knows solution for this problem?   Victor Polyakov ([EMAIL PROTECTED])
