Looking for the ESP node is useful to shortcut things but if we're told that the node is not referenced in fstab that doesn't necessarily mean that ESP is not mounted via fstab. Indeed the check is not reliable in all cases. Firstly because it assumes that udev already set the symlinks up. This is not the case for initrd-less boots. Secondly the devname of the ESP partition can be wrongly constructed by the dissect code. For example, the approach which consists in appending "p<partnum>" suffix to construct the partition devname from the disk devname doesn't work for DM devices. Hence this patch makes the logic more defensive and do not mount neither ESP nor XBOOTLDR automatically if any path in paths that starts with /efi or /boot exists.
