There should be a way to make relative symlinks #66

Closed daleglass closed 3 years ago

daleglass commented 3 years ago

The symlinks being created point to the full path on disk. I'd like to be able to create relative symlinks, so that I can move the data around and back it up and have everything keep working.

Hiho I searched for the same thing, as you can see there is an entry in the man page about this:

https://github.com/pauldreik/rdfind/blob/fa7752d6205e2071a758e7aa2d4e1c541aa96a6e/rdfind.1#L158-L160

You can use https://github.com/brandt/symlinks#convert-absolute-symlink-to-relative for that purpose.

Sorry for the late reply. I made the links absolute, because making correct relative symlinks seems nontrivial, given that parts of the paths could be relative, different mount points, hardlinks etc. Maybe I am wrong? Perhaps one could consider an opportunistic approach, where a pure text based manipulation is done, and if the candidate resolves to the same inode, pick that candidate. Else bail out and make it absolute.

Here is an issue showing it is not trivial to make this correct: https://github.com/brandt/symlinks/issues/3
