UV hardlink files

[Naramsim]

Hi @FallenDeity @phalt

on my machine when installing the dependencies with make install-base I got a warning:

Warning: Failed to hardlink files; falling back to full copy. This may lead to degraded performance.
         If the cache and target directories are on different filesystems, hardlinking may not be supported.
         If this is intentional, set `export UV_LINK_MODE=copy` or use `--link-mode=copy` to suppress this warning.
Installed 22 packages in 6.27s

Is it something ok? It happens on your systems as well? Should we add the --link-mode=copy as a default?

can you mention the directories/file system you are operating out of, the project dir (where .venv is created) and the UV_CACHE_DIR (this is usually some global path) looks like both of them might be on different file systems or drives which is causing this

I've never had to do that myself!

I'm working as aless in a fedora 44 machine:

 ❯ pwd
/home/aless/Documents/Github/pokeapi
❯ echo $UV_CACHE_DIR

The var isnt' set. I also found out that:

 ❯ make format
error: Failed to spawn: `ruff`
  Caused by: Permission denied (os error 13)
make: *** [Makefile:99: format] Error 2
❯ chmod +x .venv/bin/ruff
❯ make format
error: Failed to spawn: `ruff`
  Caused by: Permission denied (os error 13)
make: *** [Makefile:99: format] Error 2

If ran with sudo , bash cannot find ruff.

Note: Using CPython 3.14.6 interpreter at: /usr/bin/python3.14 I cleaned the .venv folder and ran a uv cache clean but it didn't help.
