Subject: booting with linux kernel 2.6.32.2

Hi,

I am using fedora 10.
I downloaded linux kernel 2.6.32.2 and run the follwing commands to
build and install it.

1) make defconfig
2) make
4)make modules
5)make all
6)make modules_install
7)make install

After that the contents of /boot/grub/menu.lst are:
------------------------------------------------------------------------
1 # grub.conf generated by anaconda
2 #
3 # Note that you do not have to rerun grub after making changes
to this file
4 # NOTICE: You have a /boot partition. This means that
5 # all kernel and initrd paths are relative to /boot/, eg.
6 # root (hd0,2)
7 # kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
8 # initrd /initrd-version.img
9 #boot=/dev/sda
10 default=2
11 timeout=5
12 splashimage=(hd0,2)/grub/splash.xpm.gz
13 hiddenmenu
14 title Fedora (2.6.32.2)
15 root (hd0,2)
16 kernel /vmlinuz-2.6.32.2 ro
root=UUID=80c4c9bd-8110-4f79-8bdc-dd69e38bf299
17 initrd /initrd-2.6.32.2.img
18 title Fedora (2.6.27.5-117.fc10.i686)
19 root (hd0,2)
20 kernel /vmlinuz-2.6.27.5-117.fc10.i686 ro
root=UUID=80c4c9bd-8110-4f79-8bdc-dd69e38bf299
21 initrd /initrd-2.6.27.5-117.fc10.i686.img
22 title Windows Vista
23 rootnoverify (hd0,0)
24 chainloader +1
---------------------------------------------------------------------------------------------------------
1) When I rebooted the machine and selected "Fedora (2.6.32.2)" from
grub's menu,
why fedora(old fedora 10 which was there initially) is booting instead
of linux kernel 2.6.32.2 ???

2) what does "ro root=UUID=80c4c9bd-8110-4f79-8bdc-dd69e38bf299" means
in /boot/grub/menu.lst ?

Thanks in advance.

If you do

blkid

you see all your UUID and the corresponding dev, UUID is a unique
identifier, this is why it is a long name.

For the kernel config, try to take your own in the /boot/config-2.6...
Try:

cp /boot/config-2.6... .config
make menuconfig
exit/save
make
make modules_install
make install
