The root file system is mounted r/o before /etc/fstab can be read. The
kernel will auto-detect the root fstype unless is it hard coded in the
kernel config file:
config netbsd root on ? type ffs
etc.
Since your jffs and ffs have the same superblock magic, it's a luck-of-the-draw
as to which one gets to test for the root fs first, and if jffs goes first,
it's going to "win".
