Re: who do you install freebsd without sysinstall?

Out of curiosity...

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?

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? 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.

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.
