summary: Ensure that replacing a bind with a symlink doesn't break an update
details: |
Recently, the steam snap replaced several bindings with symlinks in the
layout part, and that resulted in users not being able to update it from
the "bound" version to the "symlinked" one because snapd complained that
it couldn't update the mount namespace. The solution consists on discard
the namespace and retry again.
systems:
# the snaps aren't available for ARM.
- -ubuntu-*-arm*
