Removing tzdata seems like a bad idea. I think a small amount of code change could make the cost of keeping tzdata much lower. Virtually all of the tzdata files are less than 4 kilobytes, so most of the on-disk storage cost is block size overhead: dmt:~% du -s --apparent-size /usr/share/zoneinfo 1720 /usr/share/zoneinfo dmt:~% du -s /usr/share/zoneinfo 4780 /usr/share/zoneinfo Possible options include: a) Glue all the compiled zone info together in a single file, teach glibc and friends about it b) Glue the zone info together in a romfs image, mount it from a systemd unit c) Both of the above: glue them all together in a romfs, add a fuse/overlay fs to expose the individual files d) Mount a zoneinfo fs exported from the host A somewhat similar criticism applies to removing gconv. Pretending that applications don't have to deal with multiple character encodings is likely to be wrong, and we don't currently have any metadata to track whether a binary calls iconv() so there's no way to express the need for the gconv modules. Here again, most of these libraries are relatively small, and gluing them all together would be a decent size win: dmt:/usr/lib64/gconv% du -c *.so | tail -1 7352 total dmt:/usr/lib64/gconv% du --apparent-size -c *.so | tail -1 6448 total dmt:/usr/lib64/gconv% size -t *.so | tail -1 4778516 161368 2016 4941900 4b684c (TOTALS) Both things are possible here: we could teach rpm's find-requires to know about iconv, _and_ link all the gconv modules together. - ajax -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
