That's the problem: these do not show up in FreeBSD. And disklabel says "No 
valid disklabel found". But I can still boot into NetBSD and from there 
everything works just fine.

It should be the other way around indeed: I want to switch to FreeBSD.

Yes, I use UFS2 indeed, but then I guess it is not recommended to write to 
these partitions using FreeBSD?
Maybe I can format a zip-disk and copy things that way...

Daan.

Hello,

Shouldn't the NetBSD-partitions show up like ad1s3a, s3b, ... ? 
Typically, sXa is /, sXb is swap, c and d are reserved, from there on it's up 
to you (e to p can be mounted wherever you want) - e is /usr, typically, but 
not necessarily. I am unsure, however, if corresponding device nodes have to 
exist, and which partition is identified by what letter from FreeBSD. FreeBSD 
ordinarily names the partitions by their order on the disk.
NetBSD also has a - to my taste - excentric behaviour in naming partitions, 
much more untidy than with FreeBSD. NetBSD's / is always /dev/wdXa, no 
matter, at what position NetBSD's disklabel is on the disk (wd0a would be 
ad0s2a on FreeBSD). This shouldn't impact reading NetBSD's partitions from 
FreeBSD, though. 
Are they device nodes for each partition in your disklabel under FreeBSD? 

Hey, wait a moment, if you want to switch to NetBSD, why are you trying to 
move stuff from NetBSD's /home to your FreeBSD-disklabel (/home as well, I 
suppose)? Shouldn't it be the other way round? Or am I getting something 
wrong? 

In case you are really desperate, Linux reads disklabels from both Free- and 
NetBSD just fine; unless you use UFS2 with FreeBSD, that is (if you do, 
prepare for lots of funny read-errors...). It's just a little tricky to 
figure out what device-nodes to use for BSD's partitions, they typically show 
up like logical partitions in extended DOS partitions (/dev/hda5 and upwards)

Hope it helps, 

kind regards,

Benjamin
