v9 will not need to write to annex content files in order to lock them, so freezeContent removes the write bit in a shared repository, the same as in any other repository. checkContentWritePerm makes sure that the write perm is not set, which will let git-annex fsck fix up the permissions. Upgrading to v9 will need to fix the permissions as well, but it seems likely there will be situations where the user git-annex is running an upgrade as cannot, so it will have to leave the write bit set. In such a case, git-annex fsck can fix it later. Sponsored-by: Dartmouth College's Datalad project
