Where there is a system encrypted setup, i.e. a seperate /boot and the remainder under an encrypted LVM _or_ ordinary luks, what issues or steps need to be addressed when doing a kernel update?

That is, the distro packager finds an updated kernel for the installation.

Some distros use an 'initrd'/'initramfs' for the initial bootstrap, so would it just be the case of manually using the tool(s) to re-build those?

Would some distros do this automatically?

I know I've kept this distro-neutral but I'd like to know what general hints there are with this, thanks.

It is all automatic... if you use the package manager in *buntu, Fedora, Debian, Sabayon, Mandriva, OpenSuse, Mint ...or any other distro

If you're updating your kernel from the distribution, definitely no additional actions.

If you're updating on your own, IMO there shouldn't be any, either.

ok thanks both

Let me put it a little bit more drastically: do not seek to "update the kernel" apart from the published package-updates provided by your chosen distro. Determine what paths are made available to you by the distro, and choose one. Do not deviate in any way from their proscribed paths.

Hi, about:

I was going to post a new thread about a different update query that did _not_ involve encryption, so in light of your "drastic"...

If a distro moves onto the next major version and no longer provides updates particularly for the kernel, what can one do if one wants to keep the older version for a while but some programs or feature or security needs a later kernel?

I know it might depend on the actual distro but what about getting the kernel source from the repo of the newer version?

I ask that because the distros tweak the code relevant to their own M.O. (modus operandi) and yes I know about libraries, but there would still be underlying specifics wrt the older version I imagine.


I take from your post that just getting a fresh recent kernel source from kernel.org is a no-no
