Tool for updating a renamed source directory, retaining cache

[hirak99]

This is probably more like a question.

The issue is I have a large directory whose name / mount point is something I need to change frequently.

When I change it, the data remains, just the name changes. But it causes Unison to again scan everything in the directory and rebuild its cache, which is quite time consuming. Is there any way to tell Unison to move the cache from old directory name to the new one?

I am happy to tinker, so if there is a format reference and I have to manually write some code to update it, that is perfectly fine.

My hope is that may be it's just a matter of renaming the ~/.unison/arHASH and ~/.unison/fpHASH, after computing a new HASH for the renamed directory.

You can use the rootalias preference to let unison think the new path is equivalent to the old path, and the archives will get reused. Check the manual for details.
