before creating the HPC related Wiki,

I would like to ask for your advise on hard-linking raster maps files.

Soeren suggested this as a tip, I understand to save time and space.
Hard-linking was also mentioned inside the JEODPP (JRC) team at some point.

I have implemented hard-linking raster maps in https://gitlab.com/NikosAlexandris/r.internal.sh.
It's a shell script, does not compile. Will convert in Python, if useful.

If you hard-link files, how do you perform it?
If of your interest, what do you think about it?
What would be important considerations to pay attention to?
Would you name such a module differently?
Would you consider soft-linking in addition or instead of?
Would you add  a "dry-run" option (as in "don't do anything, just show what you want to do")?

Thank you, Nikos
