Permission error on Ubuntu 24.04

[bootchk]

I checked the things described in the docs.

RUST_DEBUG reveals little, vagga fails at the first exe with permission error.

Maybe need an apparmor whitelist https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2056555

I disabled apparmor, with no luck.

Besides changing from 23.10 to 24.04, the vagga.yaml files are no longer in my home directory, but on a separate filesystem.

Separate issue is that when I was in 23.10, !Ubuntu noble failed to find a downloadable image.

Apparently this is because 24.04 does not allow unprivileged user namespaces, for security reasons.

You can disable the security. See the Noble Numbat release notes.
