`security-apparmor-teardown` ran `aa-teardown`, which unloads every
profile including dockerd's in-memory `docker-default`. dockerd only loads
that profile when it starts, so every container start afterwards that
requests it fails until dockerd restarts. Since #1067 runs the teardown on
the GitHub runners, BuildKit failed each RUN of the swarm node image three
times (run 39332343490, 39 of 40 swarm jobs):
runc run failed: unable to start container process: error during
container init: unable to apply apparmor profile: apparmor failed to
apply profile: write .../attr/apparmor/exec: no such file or directory
The teardown now removes each loaded profile by name through securityfs
and skips `docker-default` and child profiles, which leave with their
parent. Dev hosts gain the same: no dockerd restart is needed after
`make environment-bootstrap`.
