I need an absolutely minimal chroot environment that only has a few commands to handle files & directories. No usermanagment or such. Since I want to create such an environment for every of my users, it must be really, really small.
Are there any prebuilt environments that fit my needs an are 5-10 MB (or as small as possible) ?
Or are there alternative ways to limit a user to a directory and to only a few commands?
Thanks for your help!
