Mmmm... did this get autoclosed because of the fix in nerdctl?

@AkihiroSuda did you mean this to be closed, or shall we revive it as soon as we have a new nerdctl RC with the fix?

[AkihiroSuda]

msg="getwd: no such file or directory" still remains

getwd looked into above ^

I am more baffled by the other failure, which seems to be that (docker) runc is not allowed to pivot root (because... apparmor?). Are we missing a step in the installation flow?

Do you have a clue what's going on with this?
