It should see them as SCSI disks, note that if you plug them in after=20 the installer boots you will need to go into Options and tell it to=20 rescan the devices. > I haven't really used USB flash for many years, but I remember when > they first started appearing on the shelves, they got well known for > their horrible reliability (stick would die within a year of use, > etc).

I would expect one to last a long time if you only use it for /boot and=20 use ZFS for the rest (or even just moving /var onto ZFS would save=20 heaps of writes). Also, you could setup 2 USB sticks (install on one then dd onto the=20 other) so you have a cold spare. =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart1260295.JiKEJ7TCrH Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iD8DBQBKJO215ZPcIHs/zowRAgg0AJ4uF3Dr6ChIaXBDFCuBka4vArOAZQCfRe4p iEHlF56WmqpaSqrd2i1IH3E= =is/n -----END PGP SIGNATURE----- --nextPart1260295.JiKEJ7TCrH--
