Command to fix existing installations?

[jaredjeya]

I have julia installed on a Linux-based computing cluster. However, the cluster is rather aggressive about cleaning out files that haven't been used recently, even sometimes getting confused by symlinks, and so it keeps breaking my julia installation.

It would be really useful to have a command that "repairs" existing installations - just basically re-runs something like initial setup and checks that every file that's meant to exist, does. Right now I can't figure out how on earth to convince JuliaUp to recreate this symlink automatically, so I have to do it manually.

Seems like a bit of a tall request to detect and fix arbitrarily mangled installations. Having some system that goes around randomly deleting things is kind of a hostile environment for any software to operate in (let alone users of that software).
