> sadly yes, the init script has a bail out that stops loading policy on
the live cd

So am I understanding this correctly?

- everything in the live environment is effectively `unconfined`, and
before 24.04 this increased security exposure (no mitigations for
compromised/malicious apps) but could not break functionality (nothing
is forbidden by policy, so everything works)

- but since 24.04, `unconfined` has fewer privileges than e.g. `steam`
(it cannot create new user namespaces), so the extra security exposure
of userns is avoided, but some functionality is missing

This makes the live-image considerably less useful for the purpose I've
been using it for: as a clean-slate Ubuntu environment, where all
settings that were not manually changed are at their defaults, and
hacks/workarounds from one test cannot accidentally leak into other
tests.
