The CLI itself is fine, but the daemon sometimes hangs on startup. I
have noticed this problem on my laptop as well (x86) so it's not
specific to this build or environment, it seems.

The daemon will be called, but will not log anything, and basically hang
for sometimes minutes. I try restarting it a few times, but that doesn't
seem to work. If I wait, it usually starts up eventually.

Most of the time the daemon starts immediately, but something seems to
trigger this hang.

Once the daemon is running and logging messages, the CLI is responsive.

It will probably require a strace to figure out why Docker is hanging on
startup like this.

I haven't seen a OCI compliant runtime that is not Go, yet.

Best,
