Mounting /proc with additional options

[Todor Petkov]

Hello,

I am trying to remount /proc on Fedora 22, kernel 4.0.4-301, following
this guide
http://www.cyberciti.biz/faq/linux-hide-processes-from-other-users/

It works on RHEL/CentOS, but not on this setup. Have someone tried it on
Fedora with newer kernel?
Also, can someone tell or guide me to a manual how and which systemd
file to be changed, so the mount of /proc accepts this parameter? Of I
can use /etc/fstab?

Regards,
