I am wishing to insert this UUID in fstab-file.

[Gdsi <gdsi11@aol.com>]

Hello.
I had used the advice: "Edit /etc/fstab and comment out (type a # before everything) the line
which starts with something like:
UUID=3a64784b-9807-446a-bc39-c9011ba6ed6b swap sw",  and boot's delay  disappired. 
But now I'm worry about absent swap-partition into /etc/fstab, perhaps without cause.
I did:
------- root@debian:/home/user# mkswap -c /dev/sda3
0 bad pages
Setting up swapspace version 1, size = 2.8 GiB (2999971840 bytes)
no label, UUID=dc070520-d011-459e-a192-fcf854cc92b4
root@debian:/home/user# 
------,
 and am wishing to insert this UUID in fstab-file. May I do it?
Excuse me that I send its posts of on separate, otherwise it does not work.
Thank .
