joeyh, could you please elaborate what v7/v8 does different to v5 when unlocking? I don't get it.
I need this feature (checked out real/hardlinked files while being immutable) as well. Even if it is only a thin layer of protection it may help. Where supported, git annex may use the file immutable attributes (as discussed in https://git-annex.branchable.com/internals/lockdown/) for better protection.
Imo it's lock/unlock which isn't clear about naming/semantics. We have to things here: 1. symlink vs. direct files 2. protection against mutation. These 2 things mingle together in the current implementation they are different concepts. We can not choose any free combination of these (writable symlink into the object store makes no sense). But a little finer control would be appreciated. No idea how to do this in a concrete way.
Maybe some 'git annex protect' command to set different protection modes on content (which could be abstract, no need to comply to unix semantics. for example: appendable, writable, immutable, deletable etc. git-annex could enforce the mode lazily if not supported directly)
or 'git annex rolock' (needs better name) .. which is like unlock but makes the file immutable/write protected somehow.
