If I go with the upgrade from 10 to 10.1 instead of a new install following the instructions in UPGRADE.TXT will my 2.6.7 kernel be replaced by the 2.4.29 that is standard with 10.1?

If it will by default are there any scripts etc that will upgrade the system but leave the kernel alone?

Thanks in advance for any help

It will remove the 2.4.26 kernel, if you haven't already, and replace it with 2.4.29. it will also likely remove the vmlinuz, System.map, and config symlinks in /boot, and the linux symlink in /usr/src. Atleast this has been my experience, although I was using upgradepkg (or a program that makes use of the pkgtools such as slapt-get)

I don't know what to tell you if you're upgrading from a CD, other than you can do it all manually with upgradepkg, and skip what you don't want to upgrade.

But no, you should not lose your 2.6 kernel, although depending on how you upgrade you will want to check the symlinks mentioned.

I don't think your kernel will be replaced. On most upgrades I have done using various tools, the kernel has always remained intact, unless I have upgraded it manually.

Wow, thanks for the quick replies.

So if I've got this right after upgradepkg finishes it's stuff I re-link the vmlinuz, System.map and config files to point to the 2.6.7 versions in /boot, change the /usr/src/linux symlink to point back to /usr/src/linux-2.6.7 and I'm good to go?

Oh, I understand from the info in UPGRADE.TXT that LIL0 will not be touched so I shouldn't have anything to do there right?

And a final couple of questions: things I have compiled myself will they still work, and will xorg.conf and gnome desktop setup etc be overwritten (I will back up /etc before I start BTW, anything else I should back up too?)

Thanks again

You will need to recompile all modules that come seperate from the kernel, and any programs that are kernel-specific (if you have any).

It's a good idea to remove custom modules entries from modprobe.conf. You can leave them in modules.conf though. (2.4.x uses modules.conf, 2.6.x uses modprobe.conf.) Infact it's probably an even better idea to uninstall them altogether, if they have an installer (such as nvidia drivers), and then reinstall/compile them after the kernel upgrade.

You will definately want to update LILO, so edit your lilo.conf and make the corrections necessary. After editing lilo, make sure you re-install it with the "lilo" command. Oh and yes, check those symlinks.

As for everything else, any new config files should have ".new" appended to them, so you can use slocate to find all the .new's and then go through and replace the old ones with the new. Hopefully you don't have too many custom tweaks in those config files, so you don't have to re-write (or copy) too much from the old file to the new.
