Hi all,
I am trying to install gentoo to an embedded system and I'd like to mount
/var to RAM as tmpfs. How can I do it? I tried to add mount command into
the file /etc/conf.d/rc-extra, but it didnot work.
Regards,
Zhiwei

Mount points are specified in /etc/fstab. I mount my /var/tmp/portage
there with:
none /var/tmp/portage tmpfs defaults 0 0
You can look-up the tmpfs mount options to specify the amount of RAM.
Default is half the RAM in the system.
With that being said, your system will break horribly if you mount /var
as a tmpfs. /var is supposed to survive reboots.

This is the question. How to mount /var as a tmpfs and the system will
not break?

You can't, simple as that.
The portage data base is there. You'd have to move it elsewhere along with the
cache. Details in the portage documentation.
