Hi,

Dear Tor project: this is very bad style to keep that in /var/lib, content

It does seem that all paths used by tor are relative to DataDirectory,
which has usually been /var/lib/tor. Perhaps a new configuration option
for CacheDirectory, and moving caches to that directory, would be
useful. It would be up to packagers to actually use that option though,
a default of using DataDirectory as CacheDirectory would not be entirely
unreasonable for cases where tor is embedded in other software.

This would seem worthy of a trac ticket if someone could write one up.

Done:

I'm surprised this hasn't come up before: the existing consensus and
directory documents are 10MB+, and change every hour.

I guess disks are big nowadays…

Also, your relay will survive if you set DataDirectory to /var/cache.
But it will lose its keys every time /var/cache is cleared, which some
distributions do on restart. (This means it will take some time to
attract bandwidth and flags after a restart.)
