[Error: OCI runtime error: crun: pivot_root: Invalid argument] : Can podman be used normally on a machine with bedrock Linux 0.7.28beta?

[txmu]

txmu@hostname:~/termux-docker$ sudo ./run.sh --podman ARCH=arm
Creating new container...
Error: OCI runtime error: crun: pivot_root: Invalid argument
Error: can only create exec sessions on running containers: container state improper

(See termux/termux-docker )

I think the point is Error: OCI runtime error: crun: pivot_root: Invalid argument

podman version:4.0.3 (Installed by arch-arm)

P.S.:

txmu@hostname:~/termux-docker$ sudo ./build-all.sh --podman

[paradigm]

I'm not deeply familiar with podman, but a quick and dirty attempt to test it out and see if the basics work seem to validate that it works as expected. Based on introductory documentation I installed podman then ran

sudo podman run -it docker.io/library/busybox

and watched it download an image before finding myself in a shell in a minimal busybox-based environment. Basics seem to work as expected.

Moreover, while I personally haven't used them much, I would expect docker and podman related technologies are popular enough that were there issues I'd have seen other people inquire about it well before you did.

Your termux-docker link didn't work, but I think I found it on my own. I didn't fully understand what I was doing, but I was able to follow the podman variation of instructions in a test Bedrock environment, see similar output to what you've shown, but watch it progress past the STEP 10/16 your attempt choked on. No pivot_root error message.

While I didn't definitively rule it out, Bedrock isn't trivially/obviously the problem here.

That having been said, there's one thing we could try: restriction. Give this a go:

sudo strat -r $(brl which podman) ./run.sh --podman ARCH=arm

The need to restrict things when something isn't working as expected is covered in brl tutorial basics, the basic usage documentation, the debugging documentation, and the strat command reference documentation. If you haven't worked your way through at least brl tutorial basics or the basic usage documentation, I strongly recommend doing so. While Bedrock makes a lot just-work, the abstraction does fall apart in some circumstances and it's important to know how to recognize and manage those.
