1998-04-04 Roland McGrath <roland@baalperazim.frob.com>
Add support for a "virtual root directory" specified at startup.
* priv.h (_diskfs_chroot_directory): Declare new variable.
* opts-std-startup.c (startup_options, parse_startup_opt): New
string-valued option -C/--directory/--virtual-root/--chroot sets
_diskfs_chroot_directory.
* init-startup.c (_diskfs_chroot_directory): New variable.
(diskfs_startup_diskfs): If that's set, look up the name and
warp us to that as a virtual root directory.
* fsys-getroot.c (diskfs_S_fsys_getroot): Initialize new peropen's
shadow_root_parent to null, and shadow_root to either null or,
if _diskfs_chroot_directory is set, to diskfs_root_node.
