Some of these system tests are a bit machine-dependent, so the textual match can make them broken on some machines but not others.

A solution to the ip link output breakage would be to tell ip to output json, and then use jq to select the few fields that actually matter. Another would be to switch to python-cram (rather than the old cram.sh) and use regexp matching.

The second breakage is because your distro makes your rootfs & any submount have a shared propagation, which breaks --persist. A possible solution would be to wrap the test in another bst invocation.
