As we now strongswan app is more battery-friendly. So we should use strongswan. You hear? Use strongswan if its possible.
But googling not give me anything. I asked support and receive half of truth. But figure out the rest by myself. So lets go.

A lot of articles. And a lot of comments that tool is broken. 🙁

RAMDISK: incomplete write (6257 != 32768)
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Pid: 1, comm: swapper not tainted %kernel_ver% #1

Ok. After fresh install of centos I usually make two commands first
yum remove posftix sendmail
yum install ssmtp
So I just understand that root (and other users mail) I never receive! Lets fix it. Open /etc/aliases with you favorite nano and scroll to the bottom of the file
# Person who should get root's mail
After that lets test
echo "test message" | mail root
Check email@example.com. Thats all!

egrep ^menuentry /etc/grub2.cfg | cut -f 2 -d \'
