Question n00b question: why doesn't this mount work?

Just curious. Here is my /etc/fstab for reference:

Code:
# cat /etc/fstab 
abd69b257348ce42.b none swap sw
abd69b257348ce42.a / ffs rw 1 1
abd69b257348ce42.m /data ffs rw,nodev,nosuid 1 2
abd69b257348ce42.k /home ffs rw,nodev,nosuid 1 2
abd69b257348ce42.d /tmp ffs rw,nodev,nosuid 1 2
abd69b257348ce42.f /usr ffs rw,nodev 1 2
abd69b257348ce42.g /usr/X11R6 ffs rw,nodev 1 2
abd69b257348ce42.h /usr/local ffs rw,nodev 1 2
abd69b257348ce42.j /usr/obj ffs rw,nodev,nosuid 1 2
abd69b257348ce42.i /usr/src ffs rw,nodev,nosuid 1 2
abd69b257348ce42.e /var ffs rw,nodev,nosuid 1 2
ce18a2d362d8319e.a /altroot ffs xx 0 0
So this works:

Code:
# umount /usr/src
# mount /usr/src
# mount | grep src
/dev/sd0i on /usr/src type ffs (local, nodev, nosuid)
#
But not this:

Code:
# umount /altroot
# mount /altroot
mount: can't find fstab entry for /altroot.
# mount ce18a2d362d8319e.a /altroot
# mount | grep altroot
/dev/sd1a on /altroot type ffs (local)
I assume it's something to do with the 'xx' part of how altroot works...but it's not like I'm giving some special parameter when explicitly giving the DUID for the second mount call.

Answering my own question...

mount calls getfsspec(), which returns this struct:

Code:
 struct fstab {
                   char    *fs_spec;       /* block special device name */
                   char    *fs_file;       /* file system path prefix */
                   char    *fs_vfstype;    /* type of file system */
                   char    *fs_mntops;     /* comma separated mount options */
                   char    *fs_type;       /* rw, ro, sw, or xx */
                   int     fs_freq;        /* dump frequency, in days */
                   int     fs_passno;      /* pass number on parallel fsck */
           };
The man page for getfsspec says:

"All entries in the file with a type field equivalent to FSTAB_XX are ignored."
