*Mview chroot management

From VirtualSquare

Jump to: navigation, search

chroot is currently supported by *Mview (svn 397)

There are two different chroot supported by *Mview:

  • chroot of a real directory (not managed by any of the loaded modules) cause the kernel chroot to be invoked.

If the call succeeds (the user permissions to run chroot) *Mview takes into account the new root to provide modules with the correct global paths.

  • chroot of a virtual directory. No special permissions needed. *Mview properly transforms the virtual pathnames.

chroot does not affect open files or the current working directory.

There is a problem related to the getcwd call: All the cwd pathnames referring to the chroot-ed subtree are relative to the new root, all the remaining paths are absolute. This behavior although strange is the same used by the Linux Kernel.
