crun master require systemd >= 237

[hswong3i]

According to #331 (and some post 0.13 commits?), crun master minimal systemd requirement is now 237, which introduce installation difficulties on following OS:

CentOS 7

Default with systemd 219 which absolutely too old; BTW, we could upgrade it to 231 by using https://copr.fedorainfracloud.org/coprs/jsynacek/systemd-backports-for-centos-7/ (see #359), which works with crun 0.13

openSUSE 15.1/15.2

Default with systemd 234 which works with crun 0.13; only openSUSE Tumbleweed with systemd 245 (see #360)

Shall we simply say "not support" for above OS with crun > 0.13, or shall we trade-off some functionality in order to maximize OS compatibility?

I've tried with a static build for crun and it seems to work fine on CentOS 7, but please be aware some fixes from #357 are required.

Have you tried it? Is it an acceptable solution?

@giuseppe my primary goal is to provide an Ansible Role for crun (see #362) from source code for most supported OS; most likely static build with nix package manager could solve this problem (see #364)?

[giuseppe]

is it solved with the new static build?

[hswong3i]

Moving on for updating Ansible Role for crun with nix-based static build, once that complete my CI should looks good with CentOS and so I will come back and close this issue ;-)
