Seems that a Linux ext2fs is a dubious proposition for read-write access 
to/from NetBSD and FreeBSD, though in limited cases even ext3fs might be OK 
from NetBSD and FreeBSD read-only.  

I noticed NetBSD current source tree included an upgrade in ext2fs support 
allowing inode of 256 bytes.  I've even thought of installing NetBSD-current on 
a USB stick just to see how it would fare with ext2fs, while not disrupting my 
NetBSD 5.1_RC3 installation.  But I guess this upgrade would not include any 
ext3fs journaling features.  I don't really want to keep updating 
NetBSD-current every few days.
