As long as those +per-key directories are used, the symlinks cannot possibly be made short enough +to pack. + +There have been some +other requests for that (datalad requested it because all those per-key +directories use disk space, add to the size of the git repo, and slow down +traversal). However, git-annex relies on those directories to prevent +accidential rm -rf deleting the annexed objects and prevent some symlink +following programs from editing/corrupting the annexed objects (the +per-key directories are left mode 400 most of the time). So it would be +fairly complicated to add a tuning that eliminated those while locking +down the permissions some other way (eg, making the `yy` directories mode +400 except when one or more thread/process needs to write to them), and since +it would have to be a tuning, it would introduce a lot of conditional +complexity into the code. +"""]] |
