NetBSD stallion ...

Apparently, NetBSD support of the Second Extended FS (heirs) is partial,
just as Linux support of Berkeley FFS (heirs), and act of running fsck_ext2fs 
(8) on a journaled ext2fs counterpart may be considered imprudent,
but since there's no BUGS section there in fsck_ext2fs(8) I did it.
Consequently I've got a nice core dump (no, I can't really assist with audit -
I (i. e. me, not NetBSD ;-) ) nuked the poor thing then (BTW, would a wizard
with enough cross-platform experience suggest an FS sound for a home partition?)

Now don't you think that this is the end? :-)
I did the necessary maintance using native tools, re-booted back into NetBSD['s 
rescue system] and executed vi(1) to edit a configuration file on
another such file system. Guess what? :-)

Create a journaled ext2fs, make it dirty and run fsck_ext2fs(8) on it.
If you're feeling adventurous (C) the INSTALL document, go for vi(1).

Using native tools and file systems may be considered a work-around :-)
