I do not write the disklabel.  Sector 1 of the netbsd partition has all
zeroes.  Regarding the loading netbsd kernel this is not a problem: it
can see fictious wd0e.

mkfs.ext2 -O^dir_index /dev/sda1

I also tried revision 0 of ext2 btw

mkfs.ext2 -r0 /dev/sda1

but netbsd now supports some features -- maybe even dir_index, but I get
another big fat error when that is enabled: I enter the debugger with
issues about mtree.

Ok this might be long so here's the full process

That's clear
