-current users: Do you recompile kernels after updating?

fogpipe · 02-17-2015, 02:45 PM

And why? Or alternately why not?

chrisretusn · 02-17-2015, 05:31 PM

No. No reason to do so.

I have been playing with kernel 3.19 on a spare laptop with -current on it, just for the sake of re-learning. Its been a long time since I had to compile one.

There are a lot of reasons that compiling your own kernel that your PC can benefit from. Security, speed and stability are just a few.

No. Somewhere along the line, I should learn how to compile a kernel, but I haven't done so yet.

I am compiling kernels a lot more since I scripted it:

https://github.com/ryanpcmcquen/linu...re/kernelMe.sh

But I do not usually recompile after updates. I do, however, reinstall quite often.

I have recompiled kernels, but, have not in quite some time. Have not needed to after updating.

I recompile the Slackware kernel and take out stuff I don't need for my system (especially modules). I use it as back up in case one of my home cooked kernels fails. I have compiled my own kernels for years because of Gentoo/Funtoo/Crux/LFS usage so I consequently do it for all distros I run. These everything including the kitchen sink kernels that work OOTB are great for most users(especially on stable systems) and to have as a back up but once you "have to" compile/recompile your kernel and do it a few times, you realize that it's not that intimidating of a task. I'm running 3.18.7 with Slackware current right now.

Why do you ask?

I update my kernels periodically to the latest of Greg's stable branch kernels, but it has nothing to do with anything that goes on in -current. Like ryan, I've scripted the build process, so build effort is minimal.

I usually ony recompile kernels on older hardware where resources are limited. When I do recompile a kernel I get rid of everthing I don't need or plan on not using. I always keep a working kernel in case I take out items I needed for things to work.

I tried it but it only got this far:

Code:

./kernelMe.sh: line 197: warning: here-document at line 34 delimited by end-of-file (wanted `EOF')
./kernelMe.sh: line 198: syntax error: unexpected end of file

use the small kernel config, include the filesystem driver to not require an initrd, add a personal tag to the name to make uname looking good

mostlyharmless · 02-18-2015, 06:47 AM

No, usually before

Labinnah · 02-18-2015, 07:00 AM

I assume you use custom kernel.

No, I don't update kernel. You must only be sure that new glibc support your kernel. "Current" requires now 3.2.29 kernel, if you have newer one, you don't need update it.

I'm not a -current user, but the added support for Xbox One controllers a good enough reason for me to build a newer kernel on my desktop.

Do you have kernelMe.sh in /usr/src?

EDIT:
Try reinstalling the script, there isn't a EOF on that line, so clearly something happened in transit. For convenience I added a quick install tut at the top of the script:
