I have recently added a second swap partition for my third system (Two of which are Linux).
My aim was to have a single dedicated swap space for each of the systems so that it would not cause any problems when swap-sharing.
Making the appropriate changes to /etc/fstab, I rebooted... Only to have the first system load both of the available swap partitions.
My question is, are there any other ways a system can mount a partition other than those listed in /etc/fstab?
cat /etc/fstab output

Yet cat /proc/swaps yields

Partition table entries are not in disk order.
I tried repacking the initramfs, checked that the resume variable is not set wrong, and only one of the two systems does this.
