Well, maybe it's just me. I've started Linux on Slackware 7.1 and used 
pretty much every major and minor distribution under the sun. I know my 
way around Slackware, Debian, CentOS, FreeBSD, Gentoo, Arch and many 
more, and my favourite installer is - and will always be - Slackware's 
bone-headed NCurses installer that lets the admin do pretty much what he 
wants - and needs - to do. CentOS 5.x's text mode installer got pretty 
close, but then, for mysterious reasons, Red Hat decided to cripple it 
into oblivion. Go figure.

I love CentOS, been using it since 4.x. But frankly, CentOS 7's 
installer is an abomination.

All's well that ends well. It only took me a day and a half to figure 
out how to configure RAID 5 using the graphical assistant. Something I 
could have done in less than three minutes using fdisk and mdadm --create.

Cheers,

Niki
