Description

Running gc in the presence of by-sha256 splitstreams gives:

Error: category directory contains non-symlink

Which is probably for the best, because it doesn't know about them and would probably decide to delete them if it could find them.

We should do something sensible there. I wonder if we should take a more generic approach to symlink handling: all symlinks reachable from anything under */refs/** get to live. We can better do the checking about if the structure is correct from fsck.

Research direction

Start by reproducing gc with by-sha256 splitstreams and inspect how it handles non-symlinks in category directories. Determine how symlinks reachable from /refs/* should be preserved, and use fsck to check whether the resulting structure is valid.
