What is this virtual machine created with qemu you talk about? -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of Roland Smith Sent: Wednesday, June 06, 2007 1:01 PM To: Eric F Crist Cc: freebsd-questions@freebsd.org Subject: Re: GEOM/GELI Boot Disk Encryption On Wed, Jun 06, 2007 at 07:28:48AM -0500, Eric F Crist wrote: > Hey folks, > > I'm trying to take a system that already has a running freebsd system (or I > can start over), and make the entire system encrypted.

The /boot directory must not be encrypted, so you need to put that on a separate slice. As for the rest, maybe the following thread will help you; http://lists.freebsd.org/pipermail/freebsd-geom/2006-July/001401.html The thing is that sysinstall doesn't support creating encrypted disks, so during install, you'd have to initialize and mount the encrypted slices manually, and then resume sysinstall. Personally, I wouldn't bother encrypting anything but your own data, i.e. /home. And for backup purposes it's better to make a seperate slice for that anyway. Disk encryption is only usefull when your disk is stolen; as long as the disk is mounted, the data is readable (if permissions allow) anyway. If your /home is already a separate slice, back up your data, unmount /home and encrypt it according to geli(8). Mount your encrypted drive and restore your backup. A good idea might be to create a virtual machine with e.g. qemu, and practice on that before you screw up anything important. :-) Roland -- R.F.Smith http://www.xs4all.nl/~rsmith/ [plain text _non-HTML_ PGP/GnuPG encrypted/signed email much appreciated] pgp: 1A2B 477F 9970 BA3C 2914 B7CE 1277 EFB0 C321 A725 (KeyID: C321A725)
