[issue1839] Segfault, NULL pointer dereference in mount_mfs from LiveCD.

[Alex Hornung (via DragonFly issue tracker)]

I suggest we actually move away from mfs and use tmpfs instead. This would 
involve (at least) the following steps:
- Change the fstab for the nrelease magic to use tmpfs, but keeping the same 
options in use (i.e. size [note that mfs' size is in sectors, iirc])
- Probably expand mount_tmpfs to use FSCopy & FSPaste with an optional parameter 
'-C', as with mount_mfs, as long as we don't have a working unionfs. FSCopy and 
FSPaste can be found in newfs/fscopy.c. An alternative to this would be finally 
fixing unionfs, but that's a more complicated issue.
- Test a few installations to see if everything still works as expected with the 
new tmpfs magic. This would ideally include both x86 and x86_64.

Cheers,
Alex Hornung
