FreeBSD jail read-only filesystem warnings.

[unix-geek]

This might be an artifact of my usage of the older jcreate rather than CBSDfile (which I have started experimenting with), but when I restart the jail I just deployed for Shinobi NVR, I get some warnings from jrestart:

mkdir: /cbsd/jails/shinobi02/home: Read-only file system
cbsd warning: mountfstab: unable to create mountpoint for nullfs /cbsd/jails-data/shinobi02-data/home: /cbsd/jails/shinobi02/home
cbsd warning: mountfstab: read-only location? Skip mount for: /cbsd/jails/shinobi02/home
mkdir: /cbsd/jails/shinobi02/compat: Read-only file system
cbsd warning: mountfstab: unable to create mountpoint for nullfs /cbsd/jails-data/shinobi02-data/compat: /cbsd/jails/shinobi02/compat
cbsd warning: mountfstab: read-only location? Skip mount for: /cbsd/jails/shinobi02/compat
mkdir: /cbsd/jails/shinobi02/home: Read-only file system
mkdir: /cbsd/jails/shinobi02/compat: Read-only file system

I can see in the auto-generated fstab for the jail more or less what I'd expect to see

# cat /cbsd/jails-fstab/shinobi02/fstab

# Please do not edit this file for additional fstabs
# Use /cbsd/jails-fstab/shinobi02/fstab.local instead
/cbsd/jails-data/shinobi02-data/etc /etc nullfs rw 0 0
/cbsd/jails-data/shinobi02-data/root /root nullfs rw 0 0
/cbsd/jails-data/shinobi02-data/tmp /tmp nullfs rw 0 0
/cbsd/jails-data/shinobi02-data/home /home nullfs rw 0 0
/cbsd/jails-data/shinobi02-data/usr/local /usr/local nullfs rw 0 0
/cbsd/jails-data/shinobi02-data/compat /compat nullfs rw 0 0
/cbsd/jails-data/shinobi02-data/var /var nullfs rw 0 0
#

I'm just wondering if I've done something wrong, and if there's a way to tell the /home and /compat file systems not to mount?
