[improvement] enhance configuration file about systemd-swap HOT 4 CLOSED

Check at now please

from systemd-swap.

ok, it's better than before, it's a begin!
I'd like to understand the vm.overcommit_memory=1 setting
and why do you suggest to increase vm.swappiness since this would handle of deeper use of the swap?

from systemd-swap.

I already describe in config, what it's suggested to change vm.swappiness for prevent problems with zram and for free up more memory for io cache with zswap

For vm.overcommit_memory=1 i already write

## (for disable early OOM killer)

https://www.kernel.org/doc/Documentation/vm/overcommit-accounting

If you interested in "Why should i disable it?", i will explain applications working with Virtual Memory and by default it's allocate much more memory when you have physically on system (i.e. you can have only 8Gb of memory and have 100-200 Gb virtual memory allocated), and some times OOM can kill app, not because you don't have memory, but only because it's allocate to much memory.
And I, and not only I, don't like this thing.

So i suggest to disable too early OOM killer, because i can have swap which not used, and app get OOM (WTF?).

Sorry for bad english.

Config file has been rewritten.
