Default branch: MAIN

Refactor remaining mount_* commands to use the common pathadj()
function for resolving paths.

Make pathadj() no longer warn about symlinks. Symlinks in /dev are
regularly used in several places like LVM . The warning was also
only visible when calling a mount_* command directly as mount(8)
itself would resolve the path witout warning before passing it to
a mount_* command.

Drop main() prototype.

Add MOPT_{REL,NO}ATIME as supported by the underlying filesystems.

Does not make sense to mount this as NFS, so it is not a bug.
We can now mount multiple instances, but all of them show all the ptys.
let us get mounted multiple times.
remove -c and chroot option; they are always on now
Always do the chroot filename mapping; it is pointless not to do it.

add back old options for compatibility, but complain if specified.

don't print 2 lines of info, remove the bogus one.

Use __dead

Make `mount_ptyfs -c' actually work.

The ALTF_* are bit masks, not indices, so use 4, not 3, for the one
after 2.  Use 0x on all the values to emphasize this.

ok rmind

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

Allow ptyfs to be mounted inside a chrooted environment.

Sync with HEAD.

Sync with wrstuden-revivesa-base-2.

Remove the \n and tabs from the __COPYRIGHT() strings.
(Tweak some to use a consistent format.)

Make all mount(2) return value error checks against -1.  Some file
systems just checked != 0, breaking MNT_GETARGS.  Others worked with < 0,
but make them check against -1 too for consistency.  And sprinkle some
stylish line wrapping where appropriate.

Add additional 'sizeof args' parameter to mount(2).

use MOPT_NULL

Always check the results of getmntopts() and free them.

Fix PR#3617 and PR#3205: call realpath to convert mount points and paths to
device nodes into absolute paths before using them.

Add a missing =

Add arguments for ptyfs: slave tty group and mode, so we don't have to
hard-code them in the kernel.

Add userland glue for ptyfs.
