When the steam binary installs distribution files, it would be really
nice if the date/time info was also brought along with it, so that they
were universal between installs and systems. This would make it super
easy to do delta copies (like rsync --compare-dest), make deduplication
easier, and probably allow for many other nice things.
Unfortunately, those time stamps are not coming along, so if I want to
dedupe my files, I have to hash them, which is IO and CPU intensive.
Right now, I have something like 96GB of steam server files total, but
if I dedupe them, I really only have about 17GB. All the rest is
duplicate files.
Here are two files, both the same;
jmomo@parts-->
[~/hlds/srcds-servers]
jmomo@parts-->md5sum ./server-tf2-*/orangebox/tf/bin/server.so
96341361093e90bc2f7f553fc0b70bb3
./server-tf2-TEST1/orangebox/tf/bin/server.so
96341361093e90bc2f7f553fc0b70bb3
./server-tf2-VANILLA/orangebox/tf/bin/server.so
But they have different timestamps because they were updated separately;
jmomo@parts-->
[~/hlds/srcds-servers]

Don't suggest that I use hard links. These files span multiple hosts.
