Why 3 kernel options in my Bootloader?

TigerLinux · 02-14-2011, 06:42 PM

I am not sure what had happened?
My ubuntu bootloader has 3 kernel to choose,

Ubuntu 2.6.35-26-generic
Ubuntu 2.6.35-25-generic
Ubuntu 2.6.35-22-generic

All can boot into linux, when I use uname -a to check, it has its name as above.

Why like that?

Because security updates were downloaded and installed. This is normal.

i see, due to updates.

also they are back ups
system updates CAN and DO break things
it is a given that sometime in the life of the computer a update for something will have a bug

Ubuntu is fairly stable so ?? maybe 2 in 5 years ?? maybe
but "things happen "

and when they do, booting into the last KNOWN GOOD kernel is VERY VERY NICE OPTION TO HAVE !

I can boot them all and run as normal.
But usually I choose the latest one.

In general, after an upgrade, you test the new kernel, if it works OK, you can remove the older kernels
using your package manager

Kind regards
