Yep; and I do have a Tao.tbz; but it is sitting right in

Every night I tar -y my website files up and sent them remote.
--Whenever-I-remember, I tar up the /etc directories and ship
them to local servers. (I *really* do gotta get a plan. Never
expect 5.4 to [ct]rap out! What a wakeup call)
Oh: /boot/loader.conf is something to consider too. Thanks
much.

If it's only the data you want, try a FreeSBIE boot disk. That will

Where can I get this FreeSBIE boot disk? Is it a floppy or can I
burn a CDROM? I have a "burner" on my new Ubuntu box, but have
never burned anything but an audio CD.
This is one of the myriad things I've never heard of,
but sounds like it should be shipped with each CD boxed
set...
It is. I think all you have to do is boot the regular CD and
select live system or something like that (I don't remember the
exact label in the menu, but it should be apparent. Then you
can mount the other disk[s] and try to rescue things.
The key is "try to rescue". After fscking my filesystems
I tried a reboot and ran into the fatal trap. Now I'm back i
fixit mode. What I really want is to get the data files off
and over to another servr. Havng /etc/* and maybe /var/db/pkg/*
would be a big help. Then I could reinstall 5.3 ->5.5 and
finally over to 6.1.
If anybody nearby who understands the FreeSBIE boot disk can
stop by in the next week or two, that'd be great. Are there
ways to scp from the # Fixit environment? Or ways to recompile
kernel and world frm here?
Try chrooting in the FreeBSIE environment on the mounted device, e.g.:
mkdir /mnt/fbsd_root
mount /dev/da0s1a /mnt/fbsd_root
#mount other filesystems here--make sure that the path is relative
to /mnt/fbsd_root and follows the same sort of rules as specified in
/mnt/fbsd_root/etc/fstab!
chroot /mnt/fbsd_root /bin/tcsh # insert your shell of choice
available here.
You need to make sure that all devices are mounted properly ('/',
'/usr/', '/var', etc), and the /dev filesystems are mounted in the
chroot environment before continuing. This is basically what users do
when installing Gentoo Linux, and I don't think that you should have an
issue with it when trying to upgrade and fix your FreeBSD system because
the principle is the same. Not sure how to do the devfs filesystems, but
I'm sure someone has an idea of how it's done; IIRC it was done by the
kernel somehow.

Why go via 5.5 if you're upgrading by installing a new system on the
machine? Just go straight to 6.1.
Stuff you should backup before doing that:
/etc --- absolutely vital
/usr/local/etc --- ditto: most people have put hours of work into
port configuration files which would be painful
to have to recreate.
/var --- lots of programs keep their state in files in
/var, not to mention stuff like MYSQL DB files.
/home or /usr/home - depending on how your disk is laid out.
/root
Other stuff you might need to backup:
/usr/local/www --- if you run web sites of this machine
/usr/X11R6/lib/X11/{xdm,app-defaults,...}
--- if you've customised stuff under there
/boot/loader.conf
/usr/src/sys/i386/conf/HOSTNAME
--- these two should be mostly for reference as
their contents have changed significantly with
changes to the system.
/usr/local/share/snmp/{snmp.conf,snmpd.conf}
--- only if you run net-snmpd: for some reason it
keeps its config files here instead of under
/usr/local/etc
That covers all of the locations I know of where hand customised files
can generally be found (on machines I admin, at least). Everything else
should be replacable by running a 'make world' cycle or by using the ports.
No doubt other people do things differently, so will have a slightly different
list...
Cheers,
Matthew
