PRoot

PRoot is a user-space implementation of "chroot", "mount --bind", and "binfmt_misc". This means that users don't need any privilege or setup to do things like: using an arbitrary directory as the new root filesystem, making files accessible somewhere else in the ... [More] filesystem hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can add their own features or use PRoot as a Linux process instrumentation engine thanks to its extension mechanism. Technically PRoot relies on "ptrace", an unprivileged system-call available in every Linux kernel. [Less]

bindfs

Overviewbindfs is a FUSE filesystem for mounting a directory to another location, similarly to mount --bind. The permissions inside the mountpoint can be altered using various rules. ExamplesHere are some examples of what bindfs can do for you: Make a directory read-only. bindfs --perms=a-w ... [More] somedir somedir Share a directory with some other users without modifying /etc/group. bindfs --mirror-only=joe,bob,@wheel ~/some/dir shared Make your website available to the webserver process read-only. bindfs --owner=www --perms=0000:u=rD ~/stuff/website ~/public_html Make all new files uploaded to an FTP share owned by you and seen by everyone. bindfs --create-for-user=me --create-with-perms=u+rw,a+rD /var/ftp/uploads /var/ftp/uploads Manualbindfs --help man 1 bindfs Supportbindfs has been tested on Linux 2.4/2.6 with fuse 2.5.3+ as well as Mac OS X 10.5 with MacFUSE. Please tell me if you have tried it on another platform, such as FreeBSD. Basic installation instructions are available. All bug reports, comments and ideas are very welcome at or the issue tracker.
