MinixFS pl11 with pl9 partitions?

[dsb@goldfinch.cs.duke.edu (Scott Bigham)]

I'm in the process of setting up my new computer, and I want to upgrade
my MinixFS to pl11 in the process.  Thing is, some of the partitions on
my external hard drive were minit'ed with pl9.  I've replaced the pl9
minix.xfs with the pl11 one and everything seems to work, but that
seems way too easy.  Is the pl11 .xfs compatible with partitions
minit'ed with pl9?  Would there be any benefit in re-minit'ing them
with pl11?

Thanks.
