Varnish 4.1 - manager and cacher processes owned by "varnish" user

[Vlad Rusu]

Hi everyone, 

I noticed the user owning both varnishd processes (parent + child) is now “varnish" (or whatever user we specify in the config). I was previously using Varnish 3 in RHEL 6 and the parent process was owned by root, as the book also describes.

Looking at the Varnish 4.0 book (can’t find a 4.1 one), it still says that’s how it should be —> http://book.varnish-software.com/4.0/chapters/Tuning.html#the-parent-process-the-manager <http://book.varnish-software.com/4.0/chapters/Tuning.html#the-parent-process-the-manager>

Before I start testing diff Varnish versions on different OS versions, can you tell me if this is expected? Is it safe.. ?
