This totally misses the point.  The -root= option is for more than just
accessing the root partition.  It allows the superuser on one machine
to have write access to all of the files on all of another machine's
file systems.

This is distressing news since we are on the verge of getting some more
workstations which will put us over the 10 machine limit and break a
lot of our code.  HELP!

Does the old "change nobody to 0" kernel patch still work?
