Mounting NAS files inside schroot

I have a schroot installation that I'm using to mount filers inside a private root. I know it can be done, but I'm not sure how to do it.

Here's my schroot.conf
[something]
type=directory
description=Cough Cough Wheeze
#priority=0
groups=u_saadm,users
root-groups=root
#device=/dev/hda_vg/experimental_chroot
#mount-options=-o atime,sync,user_xattr
location=/public/apps/xxx/approot/public/
directory=/public/apps/xxx/approot/public/
run-setup-scripts=true
run-exec-scripts=true
#script-defaults=something-scripts

Open in new window


and here's my mount-defaults which U believe should be executed by run-exec-scripts and run-setup-scripts

# mount.defaults: static file system information for chroots.
# Note that the mount point will be prefixed by the chroot path
# (CHROOT_PATH)
#
# <file system> <mount point> <type> <options> <dump> <pass>

# Mount for application 
xxxx17:/vol/xxxxxx17/path/path1 /p/path1 rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=120,vers=3,timeo=600       0 0
 nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=120,vers=3,timeo=600       0 0

Open in new window


The mountpoint mounts fine in the normal fstab for the hostfile system.

I'm using schroot 1.1.5.

Any help greatly appreciated.

EDIT:

I have also attempted to mount the NFS volume outside the root and REMOUNTING it inside the root using

/public/apps/xxxxxxxxxxxxxx/fast-data7 /p/fast-data7 none rw,bind 0 0

Open in new window


With no luck

I'm not familiar with the schroot product, but use chroot from time to time. I imagine schroot woul do things for you that I do manually, such as mount /proc and start syslogd.
In the chrooted system
Is syslogd configured?
Is ther a private syslogd running?
Are there any error messages in the log files regarding the failed mounts? (also look in log files of main system)
Actually a lot of nfs functionality has moved inside the kernel recently, so that may cause you some problems. You need to start separate instances of the portmapper and probably nfsiod to work with the files inside the chroot jail. You may have to configure a separate IP address for the system's exclusive use (it's not really a separate system - the real system can see all its files).

Maybe just try looking at the logs first

The reason is because the version of schroot I'm does not include manual mounts. Compiled a newer version and it all worked.
