Is--pre-checkpoint supported when using crun?

[eriksjolund]

The podman container checkpoint option --pre-checkpoint is described in the man page like this

It only works on `runc 1.0-rc3` or `higher`.

On the other hand the crun commit 0683fec8b message mentions

This commit takes the interface as implemented in runc and implements it for crun.

My best guess is that the podman documentation is outdated.
I did a quick test on x86_64 and it seemed to work on both runc and crun.
Using --pre-checkpoint beforehand didn't speed up the final checkpoint. It took a bit longer but the results of runc and crun were similar.

I guess we remove this special mention in the man page. Any recent version should work so it seems pointless to call out a specific version these days.
