Fix non-interactive script bug on upgrade.

Complete path to rm

Ensure we are mount rw

Oops, use /boot/kernel/

Oops, use /boot/kernel/

Move pfsense_kernel.txt to /tmp and remove /boot/kernel/* contents so we
are guarantee'd a fresh kernel directory (note freebsd kernel install moves
the old kernel directory to kernel.old so this is very similar.

Remove obsoleted files after upgrade

Only signal a package reinstall on full installations.

Record prior version

Adding pre upgrade hook

Signal a package reinstall after upgrade

Do not assume that we ship uniprocessor kernel on LiveCD any longer.

Untar the complete kernel to /boot/ instead of just the kernel file itself

Nuke /usr/local/sbin/php if it exists on upgrade

Move ttys_wrap into place last.

Check value of /etc/platform when installing the correct ttys file.

Reported-by: Vivek Khera

Nuke cvs_sync.sh on upgrade now that it resides in pfSsh.php

Remove any previous MD5 sums after upgrade.

From Seth:

If index.html, fred.png or dfuife.cgi is found remove them on upgrade.

• The drop is locked in /etc/rc.firmware
• Modify ttys after the correct file is moved into place

• Drop the lock before exiting
• Fall back to RO on needed platforms before exiting

Only zap /kernels directory if it exists

• Ensure source kernel exists before blindly copying
• Move embedded ttys back into place after upgrade

Reinstall correct kernel after upgrade.

Upgrade RELENG_1 as well for embedded.
