Is this something people do? If you delete everything from all directories except /home, it might work. Otherwise, the risk of getting mixed binaries, libraries and scripts from both systems is too great. > Processor stuff: > - The machine of interest has an AMD64 processor.

I think 32-bit Linux binaries should be supported on 64-bit FreeBSD alongside 32-bit FreeBSD binaries. --------------enigBBC76AA327B46F64D9817E76 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD4DBQFIDF3cldnAQVacBcgRArkMAKDWgEQn+DM/GEvkNjfDvE96BTGvMQCXQ8hq svbSARVui7gaPlNJ/uS/gA== =dxVg -----END PGP SIGNATURE----- --------------enigBBC76AA327B46F64D9817E76--
