The location of the mtab file isn't in a nice autoconf variable in the
package that it's in. It would require spooky hacking of mount and a few
other binaries *all at the same time* to move it, and you'd be screwed if
you tried to do a live upgrade of a system to the new format. With any
luck they will get brave enough to change it once gcc 2.95.3 comes out and
they jump to 8.0. ;)
