The main issue there is that from FreeBSD you'd be working with a (say)
ext2/3 partition as /home, when you really have to be sure that FreeBSD
handles R/W flawlessly with it rather than with UFS2+SU(+J), especially
regarding crash recovery. Perhaps with FUSE that might be solid enough,
but personally I tend to trust native formats and tools better, whether
from the FreeBSD or Linux side.

I'm still not sure about that from FreeBSD's perspective. Remembering
back to '98-'99 when I salvaged years of OS/2 work, especially code, and
those disks only had 3 primary partitions ('C:', OS/2 Boot Manager, then
drives D: through I: or J: on the extended partition, but with no s4 I
still had to start at s5, with s6 the first mountable partition (after
having built the HPFS code which is still in the tree, at 9.1 anyway).
However I may be misremembering (non-ECC memory :) so perhaps Polytropon
could show us an 'ls /dev/ada0*' when it's done?
cheers, Ian
