Live Upgrade i downgrade systemu

Z Live Upgrade możliwy jest nawet downgrade systemu.
Potrzebne jest tylko archiwum z poprzednią wersją systemu.

W moim przykładzie zrobię downgrade systemu z SXCE 75 do Solaris10u4.


Montujemy płytkę instalacyjną Solarisa 10u4:

# lofiadm -a /mnt/sol-10-u4-ga-x86-dvd.iso
/dev/lofi/1
# mount -F hsfs -o ro /dev/lofi/1 /mnt/x


Upgrejdujemy puste (utworzone z opcją "-s -") środowisko uruchomieniowe:

# time luupgrade -f -n 'be3' -s /mnt/x -a /kopia_systemu_sol10u4.flar
