I'd like to report that partition slices in FreeBSD 2.1.0 and NetBSD 1.1
aren't 100% compatible.

wd2s4: raw partition size != slice size
wd2s4: start 2459520, end 3173183, size 713664
wd2s4c: start 2459520, end 3169151, size 709632
wd2s4: rejecting partition in BSD label: it isn't entirely within the slice
wd2s4: start 2459520, end 3173183, size 713664
wd2s4d: start 0, end 3169151, size 3169152
wd2s4: raw partition size != slice size
wd2s4: start 2459520, end 3173183, size 713664
wd2s4c: start 2459520, end 3169151, size 709632

- slices created using NetBSD, when FreeBSD tries to fsck them.

I regard it as a bug of both OSs that this doesn't work 100% :)

Of course, for either to change, it means being incompatible with the past..
a solution of sorts would be nice...

(No, I can't tell you what NetBSD says yet, I don't have a kernel that looks
 for any drives on the 2nd isa bus or mounts root from wd1a).

enjoy!

p.s. yes, I know I cross posted, please be sensible when replying.
