The NetBSD slice does not need to be bootable, I was playing with it and I have no significant data, so I will eventually reinstall NetBSD or OpenBSD from scratch on the first hard drive (the recipient). Yes,my e partition mounts as /usr. I'm going to include the fdisk information as soon as I can boot again on my second hard disk (is an IDE one), from which the FreeBSD slice is to be tranferred to the first drive (another IDE).
