Bug 669120

Description of problem:

Right now when you boot Fedora live media or otherwise call up Syslinux, you are greeted with:

"Welcome to Fedora-14-x86_64-Live-Desktop!"

It's not the most welcoming message though because the string is a bit unwieldy and hard-to-read. Syslinux pulls from the PRODUCT string (not sure where it is produced):

scripts/mk-images.x86: sed -i "s/@PRODUCT@/$PRODUCT/g" $MBD_BOOTTREE/syslinux.cfg 

I was hoping that string produced by pungi could be cleaned up a bit to be more friendly. Some examples I think that would be better:

- Fedora 14 (32-bit) 
- Fedora 14 (64-bit)
- Fedora 14 (32-bit DVD) 
- Fedora 14 (64-bit DVD)
- Fedora 14: KDE Plasma (32-bit) 
- Fedora 14: KDE Plasma (64-bit)
- Fedora 14: LXDE (32-bit) 
- Fedora 14: LXDE (64-bit)
- Fedora 14: Xfce (32-bit) 
- Fedora 14: Xfce (64-bit)
- Fedora 14: Electronic Lab (32-bit) 
- Fedora 14: Electronic Lab (64-bit)
- Fedora 14: Design Suite (32-bit) 
- Fedora 14: Design Suite (64-bit)
- Fedora 14: Sugar on a Stick (32-bit) 
- Fedora 14: Sugar on a Stick (64-bit)
- Fedora 14: Games Spin (32-bit) 
- Fedora 14: Games Spin (64-bit)
- Fedora 14: Security Lab (32-bit) 
- Fedora 14: Security Lab (64-bit)

So the rules I'm suggesting for the strings: 

- The default desktop is called simply "Fedora $VERSION ($ARCH)" 
- Any non-default spins are called "Fedora $VERSION: $NAME_OF_SPIN ($ARCH)" 
- The spin name is derived from either the http://fedoraproject.org/en/get-fedora-options#desktops get.fpo options page or the spins.fedoraproject.org full name for the spin. (KDE is probably updating theirs to KDE Plasma as reflected in example strings above.) 
- Put the arch in () after the name of the spin. Where arch is '32-bit', '64-bit', 'Power PC', etc. The arch names here are suggested to be consistent with what the downloads are labeled on our main web pages (get.fpo and spins.fpo) 
- If it's live media, don't indicate that, don't point it out. Only indicate if it's a DVD. If it's DVD, point it out after the arch in the ( ) 
- $VERSION should be a whole number without decimals for a final release. For test releases / release candidates it would be nice to indicate something like, '14.92 RC1' '14.91 Nightly 06 Jan 2011' but that's up to your discretion!

This is a screenshot where the text will appear in syslinux: https://fedoraproject.org/w/uploads/3/3d/Installux-syslinux-prop1-proto1-ss2.png 

Some notes:

- Using the /etc/fedora-release string won't work because that includes the Fedora codename which isn't desirable for display in syslinux

- Jesse says /etc/system-release-cpe is a more parseable release string that might be useful to work with in lieu of /etc/fedora-release

- Peter says mk-images is just passed the same things buildinstall is wrt the string

- These string changes should affect all installs, *not* only live installs.

Some TO-DOs:

- Figure out where the string is coming from
- The system info utility isn't showing the release properly on livecd's for some reason - figure out why?
