Issue body
This serves two purposes:
a) It un-breaks `main` as `5.21/candidate` has the fixes for the regressions
when mounting the overlay filesystems;
b) It lets the spread tests act as a line of defense against further LTS
regressions, without being too exposed to breakage by using something like
`latest/edge`.
