Looking further into this, it seems that FreeBSD, OpenBSD, and NetBSD all have unique partition ids to represent their diskslice and geom_bsd that translates the FreeBSD diskslices only looks for partitions with the id reserved for FreeBSD so it will never find a NetBSD or OpenBSD slice in any combination, even if it's on it's own harddrive. Do all there BSDs actually use a different format for their diskslice or why do they use different ids. If they are different, I would still expect them to be similiar. If that's the case, then it should be a simple matter in FreeBSD 5.x to write a geom that translates the other BSD diskslices as well. Are their any good resources describing the different BSD diskslice formats. I might try taking some time and maybe write a geom so FreeBSD can read them. > > > -- > I sense much NT in you. > NT leads to Bluescreen. > Bluescreen leads to downtime. > Downtime leads to suffering. > NT is the path to the darkside. > Powerful Unix is. > > Public Key: ftp://ftp.tallye.com/pub/lorenl_pubkey.asc > Fingerprint: B3B9 D669 69C9 09EC 1BCD 835A FAF3 7A46 E4A3 280C > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" -- I sense much NT in you. NT leads to Bluescreen. Bluescreen leads to downtime. Downtime leads to suffering. NT is the path to the darkside. Powerful Unix is.
