The specific problem here is that in the previous snapshot, Andrew Reisse 
had added an lmount() system call that allowed a user process to request a 
particular label be used on a mounted file system in single-label mode. 
FreeBSD is in the process of transitioning from mount() to nmount(), which 
adds a generic syntax for expressing mount arguments.  The old lmount() 
changes are in conflict with the move to nmount(), which needs cleaning.

The best solution would be to move to passing the label as an nmount() 
argument, entirely avoiding a special system call.  However, it turns out 
that mount(8) actually uses an internal mount_ufs.c rather than 
mount_ufs(8) (whoops).  I've attached a patch from Suleiman Souhlal that 
causes UFS to be mounted using mount_ufs(8) and nmount(2) instead of the 
special case in mount(8).  You'll still need to teach both the mount(8) 
front end to pass the label argument to mount_ufs(8), and then 
mount_ufs(8) to pass it as an argument to nmount(2).  Finally, we need to 
restructure the nmount code to pass the argument to the right places to 
convert it to an internalized label.

My initial take is that we need to modify vfs_donmount() to look for the 
optional "label" argument, and if present, internalize the label and then 
pass it to vfs_domount().  I'll commit a prototype of the changes #if 0, 
if you want to take a look at the user mount changes, etc.

Thanks :-)
