Thank you for putting this up! I tried to build and run the spawn_root binary with bash or /bin/bash as argument but I am getting the following:

failed to exec bash: No such file or directory
failed to exec /bin/bash: Undefined error: 0

I am on MacOS 11.5.3. Could you kindly provide some assistance?

Are you logged into the machine physically, not just over ssh? The posix_spawnattr_set_persona_np call only works if you're physically logged into the machine.

I've tested this on macOS 12.3.1 (Apple Silicon) and macOS 11.4b1 (20F5055c) (Intel) and it worked fine.

I just figured out that might be the issue as well and tried doing it on the machine physically, it works. Thanks @zhuowei !

Good to hear. (You can run it over ssh - you just need to be physically logged in as well. I didn't put this in the README since I figured most people would test it from a local terminal anyways)
