Guys, how can I make my system do not mount TMPFS at start?
I cannot umount it after, because of some files created by daemons etc.

#fstab

/dev/sda1 swap swap defaults 0 0
/dev/sda2 / xfs defaults 0 1

I even don`t get which keywords do I need to use for search that.

/dev/shm is a requirement of glibc.

It's like opening a thread in a medical training board stating "I hate kidneys".

Trivial:

$ whatis love
love: nothing appropriate.

You hate kidneys? You just don`t know how to cook em ))

Really, with 2Gb of RAM I see very fast as Firefox make my system swapping, with df swowing me that tmpfs use 1Gb.
Ok I found that I can don`t mount /tmp, and resize /run and /dev on the fly.

You seem to misunderstand how tmpfs works. You could allocate a 10GiB tmpfs instance with only 1GiB of physical RAM. These are swap backed filesystems that do not actually occupy RAM until there's files requesting the allocation. The "size" parameter is merely an upper bound.

Top or htop would tell you quite unequivocally that /dev/shm is not claiming half of your RAM as you think it is. Its maximum size defaults to half your RAM; on my desktop with 6 GB RAM it's 3 GB.
