My grub.conf has been updated!

Hi!
I just installed my old dell Latitude c610 with Win xp and Fedora 7 and it worked fine!
The first time I booted my Fedora installation it wanted to upgrade my system with 111 "files" and I didn´t check them all (not at all acctually). Everything still works fine but my grub.conf has been upgraded with an extra kernel option (is that the correct name?)
My grub.conf looks like this:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,1)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda
default=2
timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.21-1.3228.fc7)
root (hd0,1)
kernel /vmlinuz-2.6.21-1.3228.fc7 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.21-1.3228.fc7.img
title Fedora (2.6.21-1.3194.fc7)
root (hd0,1)
kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.21-1.3194.fc7.img
title Win XP
rootnoverify (hd0,0)
chainloader +1

The system boots fine on both kernels but do i need two?
Can I delete the lines in grub.conf with the old "link" and then delete the acctual kernel image?

Its a good idea to keep the previous kernel just incase of problems. You can edit the number of kernels kept in /etc/yum/pluginconf.d/installonlyn.conf. I have mine set to keep 4 The default is 2 and on next update of kernel you will find that the oldest will be removed.

Ok!
Thank you for the fast reply. I think I´ll stick with the default 2 for a wile. (but i will take a look)

What would happen if you did not do an update and let's say three kernels were released in that time. Would an update install the latest one and keep your current one. Would update give you the latest two kernels. I seem to think that the latter would happen as i have a vague recollection of it happening to me. Though it is quite possible that other fatcors led to such a situation.

It would only update to the latest kernel. It would not install all the in betweens.
