Ability to specify some bind mounts as read/write instead of read-only within jailshell

(STAFF EDIT)

I'm editing this feature request for clarity, as the original submission is extremely vague/confusing with very little specific detail.

The origin issue here is that the customer attempted to utilize a command within a jailed account that requires read/write access to /var. Specifically, /var/run/screen

Specific logic within cPanel's jailshell ensures that some bind mounts (which includes /var) are mounted as read-only on kernels that support this functionality. This would be kernel version 2.6.25 and newer. Presently, for cPanel & WHM users, this means it affects those on RHEL/CentOS 6.x.

This feature request is to allow for the customization of whether or not specific mounts (like /var in this case) are to be mounted as read-only. In this particular case, the server owner desires it to be read/write instead.

(ORIGINAL TEXT)

I'd like the ability to mount jailshell as RW instead of just RO for CentOS 6. See ticket 4563385 for more information.
