[Bug?]: After using a symbolic link to move the global cache folder to another partition, "yarn dlx" failed.

Self-service

Describe the bug

Microsoft provides a Dev Drive feature in Windows, and they recommend storing package cache, source code, and other content in this drive. I couldn't find the place to set up the global cache folder, so I used symbolic links to move Yarn's cache folder to this partition. This usually works well, but when I use the yarn dlx command, it creates a temporary project in the% TEMP% folder and then fails due to cross partition linking, like this:

[Error: EXDEV: cross-device link not permitted,  link 'C:\Users\<UserName>\AppData\Local\Yarn\Berry\index\bb\*.dat' -> 'C:\Users\<UserName>\AppData\Local\Temp\xfs-5633e527\dlx-15420\node_modules\.store\*\package\LICENSE']

To reproduce

Move Yarn's global cache folder to another partition. Create a symbolic link pointing to a new global cache folder location. Using the yarn dlx command.

Looks like you have globally set nodeLinker: pnpm? If so this is one of the limitations of the pnpm linker: your globalFolder and the project (in this case, the temporary folder) must be on the same drive because the pnpm linker needs to create hardlinks between those.
