summary: Ensure the snapd works without core on classic systems
details: |
Check that snapd can be installed without the core snap on classic
systems and that commands can re-exec into snapd.
# Run only on ubuntu classic because this re-execs. We have a
# separate test for UC18 already and on UC16 we always have a core
# snap so we don't need to test there.
systems: [ubuntu-1*-64, ubuntu-2*-64]
environment:
# uploading large snap triggers OOM
SNAPD_NO_MEMORY_LIMIT: 1
restore: |
rm -f /tmp/snapd_*.snap
execute: |
