Thanks a lot, Arthur! We have a 1k sector on older systems. I based my estimation on that, and the total count of files. Plus, our filesystem keeps symlinks in directory, not in a separate sector. if I turn more timezones into symlinks, that must save some space too.

Cutting out old data may not buy as much as you'd like. Putting a "timecnt = 0" at the top of "writezone" in "zic.c" and then comparing the produced directories of the original ("tzraw") and modified ("tzcooked") yields:
Script started on Thu, May 18, 2017 1:12:37 PM $ du -s tzraw/tmp/etc tzcooked/tmp/etc 3103 tzraw/tmp/etc 2356 tzcooked/tmp/etc $ exit exit Script done on Thu, May 18, 2017 1:12:49 PM
Limited savings is due to disk sector size; as an example, the "America/New_York" produced by an unmodified zic weighs in at 3545 bytes; on a 4096-byte-sector system, the one sector it takes can't be reduced.
(Your correspondent is enough of a fossil to have lived in the age of 512-byte sectors.)
If space is at a premium, be sure to "make REDO=posix_only ..." when building.

Hello,
I'm developing for a pretty small-sized embedded system, and 2.9M of binaries is a bit too much for us. The system never uses a date before 2007.
I estimate I can slim it down too 500K by cutting down the old data.
1. I made a script to cut down the source data: all the rules and all the zonelines before 2001. Compiling this data, I get a lot of errors like:
"northamerica", line 2537: %s in ruleless zone "northamerica", line 2618: unruly zone
because some zones are left without rules, but with %s format in them.
2. I tried to modify zic itself, but apparently understanding it will take me days. Just setting min_year to 2001 results in bunch of
can't determine time zone abbreviation to use just after until time
Does anyone have a ready solution? Thanks!
