Issues when running VS Code devcontainer as Sysbox

[felipecrs]

This issue only happens if I use debian:bullseye as base, and I copied and pasted all the contents from https://github.com/nestybox/dockerfiles/blob/master/ubuntu-focal-systemd/Dockerfile in order to install systemd in the debian:bullseye image.

I created a repository with the contents I used, it can be reproduced that way:

• https://github.com/felipecrs/sysbox-devcontainer.git

Funnily enough, if I take the exact same image which VS Code uses and use docker run on it, it works fine.

The command for testing is:

sudo sysctl kernel.dmesg_restrict=0

Although it requires the following patch on sysbox-fs first:

• https://github.com/nestybox/sysbox-fs/pull/77

PS:

• If I use ubuntu-jammy as base, it works fine always
• It's totally understandable if your prefer not to spent time investigating this issue. I spent several hours on it, and could not get further. I'm opening this issue so I can at least document this "limitation", or simply acknowledge it for future reference. Thus, feel free to also close it if you prefer to keep the backlog clean.
