Description ota 2006-09-23 03:10:21 UTC 
This patch helps and enhances to mount md-based device such as uzip,
slice/partitions, and so on.

If mount_md is created with this patch such that we can add md-devices to
fstab, possibilities of md-device will greatly expand.


This is how to take advantage of this patch.  These examples can be written
/etc/fstab as well with mount_md.

How-To-Repeat: N/A: current mdmfs does not allow this.

Comment 4 Yar Tikhiy 2007-03-07 11:44:21 UTC 
Please note that there is a bug in the patch.  It is described in
kern/109863 and has been fixed in mdmfs.c rev. 1.31.  The fix should
be a part of the MFC so that RELENG_6 isn't buggy from the outset.
