mount: Skip LABEL=root filesystems

[cgwalters]

Part of supporting overriding the rootfs. We don't want to try
to mount this, as it will already have been taken care of by
the initramfs. Similarly for unmount.

You aren't required to have a path for mount. Ignition doesn't actually have any contract about FS labels.

Hm right. So it's more a FCOS convention/API that we have a LABEL=root filesystem. How about adding --skip=label=root as an argument to ignition --stage=mount?

Ignition should already skip any filesystem entries that don't have a path.

Oh, got it now! I updated this then and yep, seems to work. Thanks!
