Yeah I thought about that after.

Then I tried to replace 64bits binaries and libs with 32bit
ones from
another box but it didn't work (saying it can't run these
ELF binaries).

And another thing came up: I cannot use most of the binaries
that came
with linux (64 bit) emulation too. Most core dump (the kdump
for 64bit
Linux date is attached).

I may find the time to try and do that (after submitting
some PR I have).
But as I lack experience in pkgsrc/netbsd development (just
did some small
projects at school), could you give me a few hints?

Are you placing the 32-bit binaries under /emul/linux32? 
The
directory /emul/linux is for an x86_64 environment.

You could modify the installation directory of the suse100
packages to
install to emul/linux32.

As Blair said, 64bit binaries needs to be in `/emul/linux'
subtree,
and 32bit in `/emul/linux32'.

I did not see anything obvious with your trace. Can you try
to modify
emul.linux.kern.osrelease to emulate a 2.6 Linux kernel ?

njolylanfeust [~]> sysctl emul
emul.linux.kern.ostype = Linux
emul.linux.kern.osrelease = 2.6.22
emul.linux.kern.osversion = #0 Wed Feb 20 20:00:02 CET 2002
emul.linux32.kern.ostype = Linux
emul.linux32.kern.osrelease = 2.4.18
emul.linux32.kern.osversion = #0 Wed Feb 20 20:00:02 CET
2002

The main idea was to create suse100-32 compat packages by
using most
of the current suse100 infrastructure. I thought that simply
including
the suse100 Makefile would do most of the trick, but we need
to
redefine some variables such as SUSE_ARCH, MACHINE_ARCH,
EMULSUBDIR,
etc...

I'll try to set up a message about this to tech-pkg later
today.

Ok. If you do think this the correct way to handle this ...
let's go
for it.

Thanks for your great work.
