    Do you still have the shell script?

    Also clarification:  The panic occured while you were doing the mounts,
    not while it was doing a build or running utilities or other things
    inside the mounts?
Nothing.  I was setting up the chroot for use.  The shell script did exactly these steps:

cat init_client.sh 
#!/bin/sh

client=$1

cd "$client"
mount -t null -o ro /pbulk/root root
mount -t null var root/var
mount -t null tmp root/tmp
mount -t null dev root/dev
mount -t null usr.pkg root/usr/pkg
mount -t null /pbulk/scratch root/pbulk/scratch
mount -t null /pbulk/packages root/pbulk/packages
mount -t null /pbulk/distfiles root/pbulk/distfiles
mount -t null /pbulk/bulklog root/pbulk/bulklog
mount -t null -o ro /pbulk/pkgsrc root/usr/pkgsrc
the /pbulk, /pbulk2, /pbulk/root, /pbulk/clients mounts were done manually before.
