Hi Oliver

Thanks for looking into this:

What I want to achieve is: disabled root ssh login (already works), and having only few users in a "su" group, that are able to execute the su, to be able to su to the root user and manage the system. I want all users to be chrooted and only those in the "su"group can su.

Hi all,

I'm having a little problem with setting up the jailkit properly in
order to use su as a chrooted user.

what exactly do want to achieve? having 'su' inside a chroot jail is not
very common. su is a setuid binary (not recommended in a jail) and it
probably needs access to the shadow file (not in the jail) to check

perhaps there are other (more secure) ways to accomplish what you want
to do.
