summary: Check that command-chain is properly supported
|
|
|
|
details: |
|
|
Verify the command-chain feature works as expected for hooks, apps, and
|
|
services. Rather than running the hook, app, or service directly, the
|
|
command-chain should be prefixed to the target command. Additionally verify
|
|
that the command-chain is executed when running a snap with `snap run
|
|
--shell`.
|
|
|
|
systems:
|
|
# uubuntu 32bit: test uses snap with base core20 which there is no 32bit
|
|
# variant of
|
|
- -ubuntu-*-32
|
|
|
|
environment:
|
|
# Ensure that running purely from the deb (without re-exec) works
|
|
# correctly
