I don't have anything beyond basic rwxrwxrwx permissions, but I do
have those. It doesn't look like cpio will preserve them?

I haven't had to deal with this on a Linux box before - will I need to
deal with any open files issues? Per ps -ae, I've got the following
processes running at the moment:

acpid           dovecot         init            kthreadd        rpc.mountd
afpd            dovecot-auth    kacpid          lockd           rpc.statd
aio/0           emacs           kacpi_notify    mailmanctl      rsyslogd
apache2         events/0        kblockd/0       migration/0     smbd
ata/0           exim4           kgameportd      mutt            sort
ata_aux         famd            khelper         nfsd            sshd
atalkd          getty           khubd           nfsd4           su
bash            hald            kjournald       nmbd            udevd
CMD             hald-addon-acpi kondemand/0     papd            uniq
column          hald-addon-inpu kpsmoused       pdflush         watchdog/0
cron            hald-addon-stor kseriod         portmap         winbindd
cupsd           hald-runner     ksoftirqd/0     ps
cut             imap-login      ksuspend_usbd   python
dbus-daemon     inetd           kswapd0         rpciod/0

Some I know I don't have to worry about - emacs, sort, uniq, ps, cut,
and column are all due to this e-mail message. I should be able to get
rid of most of the k* processes by changing to a lower run-level - I
never use X on this box anyway. The rest? I know I can manually shut a
bunch of them down (apache2, the imap stuff, probably cups, exim,
samba).
