I wonder if just adding CentOS 9 would be enough. Because in CI we test just
compilation. The point of the public CI is to test the oldest distros, newest
distros and something in between, that should cover the most of compilation
problems (no need to test *all* used distros to be safe).
But sure, both can stay if you want. The runtime is still reasonable.
NOTE: I did not care much in case of iputils, which have much faster build than
LTP.

If we want to add both CentOS 8 and 9, we could remove some of debian:oldstable (bullseye)
(similar kernel).

And, we could add just openSUSE Leap 42.2, which has older glibc and gcc than
Ubuntu 16.04 LTS xenial. For sure there are more people which use xenial than
old Leap 42.2, but as I said, the goal is to test the oldest distro we
maintainers really care about (and do not have extra work for nothing, which is
IMHO keeping CentOS 7 compilable).

WDYT?

Kind regards,
Petr
