alpineSWAP
the headache .... manually setup disks in alpine and swap was not getting activated on boot...here's the solutions.
blkid
<-- get the swap disk UUID
vi /etc/fstab
UUID=51b5d84d-464b-4407-acfa-224ccff7b32a swap swap defaults 0 0
## WTF - have to start 'swap' service....making it go up at boot.
rc-update -v add swap boot
## verify it's been added to runlevel boot
rc-update
