zsh restricted mode... need cd back

zsh restricted mode... need cd back

[root]

I want to run zsh in restricted mode but still have cd ability (at least
in thier home directories and no lower)
but I have 2 problems... 1. I can not seem to be able to run it in
restricted mode and I ahve read all the documentation I can before
asking you guys.. and 2. I can not find where it restricts the cd
ability in the source code so I can bring it back

No lower?  You mean, no closer to the root?  Or do you only want them to be
able to make one-level-deep subtrees for some reason?

There are two ways to run in restricted mode: put "setopt restricted" in
/etc/zshenv (not recommended), or make a link from zsh to a name that
starts with the letter "r" (such as "rzsh") and run zsh through that link.

Note that restricted mode first appeared in 3.1.something, so you can't
run in restricted mode at all using 3.0.5.  You can get close, but not
all the way there.

It's in Src/builtin.c in bin_cd().

However, it may be that what you really want is to "chroot" them to a
limited subtree of the filesystem.
