Hi Mathieu,

failure from the 262 upgrade related to kernel version.

I built both, systemd as init, and checked directly:

   6.18.52:
     # systemd-coredump --check-requirements; echo $?
     ioctl(PIDFD_GET_INFO) does not support PIDFD_INFO_COREDUMP and/or 
PIDFD_INFO_COREDUMP_SIGNAL.
     1
     -> coredumpd goes to failed (start-limit-hit), test_systemd_failed 
fails

   7.2.6:
     # systemd-coredump --check-requirements; echo $?
     0
     -> coredumpd is active (running), test passes

But PIDFD_INFO_COREDUMP_SIGNAL is available from kernel version 6.19.

But below NEWS doesn't say anything about version requirements.


NEWS (https://github.com/systemd/systemd/blob/v262-stable/NEWS#L370) says

         * systemd-coredump now supports the kernel coredump socket protocol
           available since Linux 6.17. On supported kernels,
           systemd-coredumpd.service listens on 
/run/systemd/coredumpd/kernel,
           and systemd-coredump-register.service registers the socket 
through
           kernel.core_pattern. Older kernels continue to use the 
per-coredump
           systemd-coredump@.service path. Changes to coredump.conf require
           reloading systemd-coredumpd.service, and deployments that set a
           custom kernel.core_pattern should stop and disable that service.

But looks like older kernel logic is not working as expected.

One solution is use ConditionKernelVersion and skip that test on 
versions less than 6.19
