As root, I changed the time zone with tzconfig to PST.
But the change cannot be saved because KNOPPIX tells
me that /etc/timezone is on the READ-ONLY filesystem.
As long as my system is running my time zone stays at PST.
But after a reboot, it goes back to the CET time zone.
(And I have to update the time zone again.)
How do I make the PST time zone permanent?
