kernel installer script

[pidsley]

I wrote this a while ago, thinking it might stop some of the whining about bbq releases without rolling kernels by making installing new kernels slightly easier. The script attempts to build a list of all available kernels from your sources (and gives you the option of adding liquorix and siduction sources if you don't have them) and then presents that list in a dialog and allows you to choose one to install. At rhowaldt's suggestion, you can specify that you only want to see the rolling options, or you can see all available kernels. Joe tested it, and I just used it again this morning to install the 3.13 towo kernel. I hope someone finds it useful.

As always, there are probably better ways to do everything in this script. As Joe says "The complexity of the implementation is determined by the intended usage."

aaah nice, you released this now, good shit pidsley, and thanks for adding my suggestion to it :)

[dkeg]

great one pids. should be included in future releases.

[machinebacon]

thanks pids, will be included in the bbqmenu's system options :)

[wuxmedia]

neato, proper scripting.
Thanks Pids.

Cool one, thanks for this.

Looks very nice. smxi does this easily too, though.

There's always room to innovate. Remember Henry Ford didn't invent the car, nor the assembly line.
He just brought them together.

Heinz Hot Sauce vs. Dad's family recipe. I take the latter. ;) (Now guess which one pid's is)

When pulling new kernels, I now use this script. It does exactly what it says on the box.

[GekkoP]

^ Same here.

Good script, pidsley.
Nice style too.
One remark: installing a new kernel automatically triggers a grub-update.
No need to run an extra one.

I will be using this too.
Thanks

Thank you for the reminder about update-grub. I realized this a few days ago and have now removed the update-grub code in the latest release on github. I might make it optional just in case. :)

[machinebacon]

@xaos52: /etc/kernel/postinst.d/zz-update-grub
only if this (or a similar) script is existing the update-grub is triggered, so @pidsley: you can make a test if the file exists and let update-grub be called if the file does not exist.

[pidsley]

Thanks bacon. Is this file always present in bbq spins (unless the user has deleted or renamed it)?

[xaos52]

/etc/kernel/postinst.d/zz-update-grub is installed when you install grub- more precisely any of the existing grub packages.
If grub is installed on your system, any kernel install will trigger update-grub, so you don't have to re-run it.
if grub is not installed on your system and you do a kernel install, grub-install is not triggered, and should not be run manually either.

Conclusion: whether grub is installed or not, you should not run grub-install at the end of the script

[machinebacon]

^Why *should the user not* run it? I'd say: if, then it should also run ../initramfs-tools. And if you say "it should not", I can point you to a bunch of threads in this and other forums that not every kernel upgrade runs these scripts ;)

[xaos52]

OK.
But asking to run it after it has just finished is ... not looking good.

Suggestion:
test if /boot/grub/grub.cfg is newer than tmpfile. If it is, grub-update has been run by the script and there is no need to ask the question to run it again.

Just trying to make it better than it is already. :)
