I think it would be better if tzdata would copy the updated localtime
file from /usr/share/zoneinfo/... (via %post) when upgrading depending
on ZONE in /etc/sysconfig/clock. To allow custom timezones (real
customized tz files or timezones the config tools don't know about) I
propose to use ZONE=custom upon which neither tzdata nor
system-config-date would touch /etc/localtime. Petr, what do you think?
