mount fdescfs in Jail for Bash

[Chillons]

Hi

I recently installed Bash in a Jail. Bash requires fdescfs for full functionality. The following note gets displayed:

Code:

===========================================================================
Message from bash-4.3.42_1:
======================================================================

bash requires fdescfs(5) mounted on /dev/fd

If you have not done it yet, please do the following:

    mount -t fdescfs fdesc /dev/fd

To make it permanent, you need the following lines in /etc/fstab:

    fdesc    /dev/fd        fdescfs        rw    0    0

If I try to mount it in a jail i get a permission denied error.

Code:

root@jail:/ # mount -t fdescfs fdesc /dev/fd

mount: fdesc: Operation not permitted

I found this link, but it does not explain where the line "jail_jboss6_fdescfs_enable="YES" # mount fdescfs in the jail" should be put.

How to provide fdescfs to a jail? Where should this be put to make it permanently?

it does not explain where the line "jail_jboss6_fdescfs_enable="YES" # mount fdescfs in the jail" should be put.

Looks like an rc.conf tunable on the FreeNAS system. No idea whether or not it will work or not though.
