Regarding the zoneinfo files, what's the minimum I can get away with and still be able to support all timezones (this is for a product that will be marketed all over North America, Europe and Asia, perhaps elsewhere).
Can I just copy /usr/share/zoneinfo/posix from Slackware-current into /usr/share/zoneinfo on the board and be okay with everything? I presume the tzdata files are portable? If not I can probably extract them from the Debian tzdata package.
The system will be running a custom uClibc based linux setup, with busybox, dropbear and some custom apps.
