Hello everybody! I need to add a swap partition from ubuntu that I alreay installed on the same computer to Slitaz. Is there any way to add this swap partition? The reason was that it didn't show up any swap partition during installation. Thanks!

Slitaz would pick up the existing swap partition at boot and there is no necessity to add a swap partition during installation. Normally there is a message in the boot log to this effect.

And as in Slitaz know what swap is connected?

Thank you.
My English is very bad, so I use the on-line translator.
In a large linux I could get information on the use of swap command [c]swapon -s (display summary about used swap devices and exit)[/c]. But in BusyBox, which is used in the Slitaz command [c]swapon[/c] has only two options: [c]-a[/c] and [c]-p PRI[/c].
Therefore it is not clear how do I know I have connected swap or not.

Hi black dog & mojo!
Another answer for the question. Show boot log:
[c]tux@slitaz:~$ su

root@slitaz:/home/tux# fdisk -l | grep swap
/dev/sda5 18022 18151 1044193+ 82 Linux swap

Thank you!
Command [c]free[/c] really shows the presence swap.
To determine swap the ID of partition must specify as 82?
If the installation ID to swap partition is not 82, then swap will not be defined?

Hi black dog,
Your screenshot really surprized me. Here 83 for Linux ext2/3/4 filesystem.
Please, post here your /etc/fstab.

What is the output of :
# blkid

I apologize.
The fact that I deliberately changed the ID section to show that in the output of [c]fdisk -l[/c] is not a word "swap".
In this case, the presence of swap is determined by the fstab.
But if at the beginning of the section ID will be 83, not 82, then this section will not be defined as a swap in fstab is not the record.
Is this true?

Dear black dog,
Experiments in the Linux are great things! You can try to connect your ext3 partition as swap (using swapon command). But... you'll fail. Why?
You can connect both swap partition or swap file (recently I've used windows' pagefile.sys as additional swap). But before using your partition (or file) you should prepare it, or you'll get error else.
Command for preparing swap partition is [c]mkswap[/c], you can find it syntax in the internet (using DuckDuckGo). Partitioning program (gparted) usually prepared swap partition for you.
Sorry, but I can't reach the sense in your actions. Why you fool your system? You couldn't use same partition both for swap and file storing at the same time.

Indeed, I do not really understand explain. 
Gparted program during partition creation swap, sets it as the ID 82. And this section is defined as a swap and properly registers in fstab.
But I also set slitaz-base. And use the command [c]fdisk[/c] and [c]mkswap[/c]. [c]Mkswap[/c] command does not change the ID section. Therefore created section is not defined as a swap.
True, it was my suspicion. I did not know the command [c]free[/c], to check whether you have connected swap. And in fstab no record sharing swap.
Only then I realized change ID section and it worked.
Although we can not rule out the fact that my problems were due to swap for other reasons.
I hope that the topic was not offended, I climbed up here.

explain? 
K.I.S.S.
If I want swap then I open GPartEd and make swap. That's all from my side.
In other side, system find and use this swap automagically.
If you have no X, you can use fdisk & mkswap instead of. But why anyone wants to change partition id?

Thank you!
