The last line works fine.
Was an obsolete entry of "UUID=[THE_UUID]  none  swap sw  0 0" form.
Now boots *FASTER* and without any error/warning messages ;}!
Thanks.

Should be in /var/log/boot or dmesg.  I can't remember if stretch uses
systemd, but if it does, you'll likely need some invocation of
journalctl (but I don't have a system to verify a quick google search,
so don't want to lead too far astray)

have an entry in /etc/fstab to load the swap.

    UUID=[THE_UUID]  none  swap sw  0 0

or with your /dev/sda5

    /dev/sda5  none  swap  0  0

I use Devuan (and a few others) with such lines

# file /etc/fstab
/dev/sda7   /        ext4  defaults          0  0
/dev/sda10  swap     swap  defaults,nofail   0  0
/dev/sdb15  /0/adt   ext4  defaults,nofail   0  2
/dev/sdc9   /0/local ext4  defaults,nofail   0  2
#

The 'nofail' means that a no-find of an otherwise unessential mount will
NOT stall/fail the boot. I used device-names in the above to prevent
line-breaks but actually use UUID because with several SATA disks
plugged-in all the time device-name confusion is not unthinkable. I
always thought that there should be a kernel argumewnt to massively slow
down the boot and arm 2 keys for interventions: one for snapshots and
another for stepping the process *when I want to trouble-shoot it*.
