SandboxIt

Simple to use sandboxing script (WIP / proof of concept code)

Using bubblewrap and fuse, redirects program away from your personal data, while sill allowing read-only access to system files.

Usage examples:
[user@pc RimWorld]$ sandboxit.py ./RimWorldLinux.x86_64
[user@pc ~]$ sandboxit.py discord

Creates sandbox linked to program and runs that program in it. Same program is always started in same sandbox, so it can, for example, load saved game states from before.

[user@pc Observer]$ sandboxit.py -b GAMES ./TheObserver.sh

Runs program in sandbox named GAMES.

sandboxit.py -v --for ./RimWorldLinux.x86_64 mc

Runs Midnight Commander in sandbox of other program, so it can be explored freely. This works with anything, not just mc. bash may be especially useful.

  • python
  • optionaly fusepy, for redirecting write operations to sandbox storage
