Default Grub2 upgrade issue.

I'm working on upgrading my classroom lab from Fedora 14 to 16
and doing a test on one system. Most things have gone ok with a
few issues.

1. X11 didn't come up after the upgrade from dvd, but deleting
xorg.conf fixed that.
2. Running yum update afterwards would found over 400 updates,
but it would crash even with --skip-broken. Fixed that by using
yumex, and doing small groups of updates, and then skipping just
the ones that caused problem.
3. Desktop icons missing from programs that were there before.
installing gnome-tweak-tool seems to have gotten what I want.
4. Issue with grub.conf update. Didn't notice that there was a
change in the grub process. The new grub2 got the Fedora
options, and the os-probe seems to have gotten the XP that is on
the machine. Two other options that were in the original xorg.conf
are missing, and the memtest was also gone. Got memtest by just
running the setup process, but not clear what would be the best
option for the other two. Perhaps the 40_custom. Remotely
accessing the system from home via VNC, so thought might get
some expert advice.

Here are the old lines from the grub.conf

title G4L
kernel /bz3x1.4 ramdisk_size=65536 root=/dev/ram0
telnetd=yes
initrd /ramdisk.lzma
title G4L Restore XP
kernel /bz3x1.4 ramdisk_size=65536 root=/dev/ram0
telnetd=yes run="mount /dev/sda6 /mnt/local && cd /mnt/local &&
./reimagexp "
initrd /ramdisk.lzma

The first option loads my diskimaging project into ram and allows
access from anther machine behind the firewall to run it remotely.

The second option is able to restore the Windows XP from an
ntfsclone image stored on /dev/sda6, which allows the quick
restore of the XP in about 10 minutes for any reason.

package-cleanup has options that may be able to help with this,
specifically --orphans, --problems, and --dupes. See "man
package-cleanup" for more info.

Yup, just add your new entries to 40_custom and rerun grub2-mkconfig.

You'll need to rewrite them for GRUB2. Arch Linux has an good
overview of writing custom GRUB2 entries:
https://wiki.archlinux.org/index.php/GRUB2#Configuration

And, the complete syntax for GRUB2 menu entries is listed in their manual:
http://www.gnu.org/software/grub/manual/grub.html
