So If I made a custom boot cd I could boot a dead box, setup the drives and slices, CVSUP the system I want to build, tweak the build environment for the proper temporary build locations and build a system from source and install that system to the now live box, boot it and be done? I've always wondered about this because I always remake the system I've just installed because I'm usually dealing with deprecated hardware and all the architecture tweaks I could use help... If that run on is confusing basically to setup FreeBSD like a gentoo install from scratch with a system CD. also along these lines how do I make the system allow me to seed the entropy engine? Usually after an install it asks to fill in a screen full of junk, but with a custom install it doesn't do this for me, at least not the last time I tried. Just curious, especially if I attempt the above procedure. -brian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Basically yes. When booting from CD though, I'll have to mdconfig(8) and re-mount at least /tmp, maybe /var as well. also along these lines how do I make the system allow me to seed the entropy engine?

Well, it does this only if the below conditions are met: 1) You have enabled sshd(8) in sysinstall(8), so it's enabled in /etc/rc.conf. 2) This is the first boot, /etc/rc.d/sshd needs to generate new SSH keys but random(4) hasn't been seeded yet. (random(4) is seeded by the /random and /var/db/random/* files.) So, if you did a custom install and then rebooted for the first time, but did not yet enable sshd(8), the cron(8) will save some entropy, so the time you need it to generate SSH keys there will already be some entropy available. But if you absolutely need to reseed manually, boot into single-user mode, and type rm /entropy /var/db/entropy/* Then proceed with normal booting. If sshd(8) is enabled, it will ask you to enter some entropy. Cheers, -- Ruslan Ermilov [EMAIL PROTECTED] FreeBSD committer pgpqXXoIcTwku.pgp Description: PGP signature

Cheers, -- Ruslan Ermilov [EMAIL PROTECTED] FreeBSD committer ok, I figured it was something simple enough like that... how does cron save entropy??? I've noticed saving entropy files at shutdown but have always wondered what it is using. or does it just read from /dev/random? -brian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

The latter saves some amount of /dev/random for further
seeding. /entropy is saved by /etc/rc.d/random, when
it stops.
random_stop()
{
# Write some entropy so when the machine reboots /dev/random
# can be reseeded
#
I think two mechanisms exist because a solution involving
cron(8) works better, but cron(8) is not guaranteed to be
up and running (untypical but anyway), so additionally an
entropy is also saved once on shutdown.
