It is observed that systemd-coredump has the capability to remove
the older dumps which are having the naming style mentioned in
/proc/sys/kernel/core_pattern, But will not remove any other files
present in the coredump directory.
It can happen that, while processing a dump the BMC Crashes and there
by leaving the partial dumps in the coredump directory and these will
be hidden and will not be removed by systemd-coredump service.These
files can get piled up and the BMC can run into OOM condition.So idea
of this commit is to make sure that , we remove all the temporary
hidden files in the coredump directory during the next BMC boot.
- Made a rule and placed it in /usr/lib/tmpfiles.d/*.conf which will
be used by systemd-tmpfiles to remove the hidden files in coredump
directory during boot.
Partially Resolves openbmc/openbmc#2826
