Talk:HOWTO: Upgrade kernel using Entropy

I have got a suggestion for how to search which modules are installed for one's kernel version: Instead of running
equo search <kernel-version> > kernel-upgrade.txt
(BTW, the pipe is unnecessary. You can redirect the output of equo directly to another file.)
run
equo query installed <kernel-version> > kernel-upgrade.txt
This way you will only see packages that are actually installed on your machine, thus not having to search the text-file to find out, which kernel-modules are installed, and which ones aren't. Be careful though, to really only update your kernel-modules!
E.g. I did an upgrade from 2.6.35 to 2.6.36, and in my kernel-upgrade.txt there was also this package listed:
sys-apps/iproute2-2.6.35-r2
This is NOT a kernel module! But if one reads the Description of the packages listed this is quite easy to find out.

Good idea, but if you append "-sabayon" to the kernel version then you won't even get that one 'rogue' package you listed. For example, the following would do it:
equo query installed 2.6.35-sabayon
resulting in:

In fact, one could filter the package names out of that by using grep like so:
# equo query installed 2.6.35-sabayon | grep '#'
For example:
# equo query installed 2.6.35-sabayon | grep '#' >> @@ Package: app-emulation/virtualbox-guest-additions-3.2.8#2.6.35-sabayon branch: 5, [__system__] >> @@ Package: net-wireless/broadcom-sta-5.60.48.36-r1#2.6.35-sabayon branch: 5, [__system__] >> @@ Package: net-wireless/ndiswrapper-1.56#2.6.35-sabayon branch: 5, [__system__] >> @@ Package: x11-drivers/ati-drivers-10.8#2.6.35-sabayon branch: 5, [__system__] >> @@ Package: x11-drivers/nvidia-drivers-256.53#2.6.35-sabayon branch: 5, [__system__] >> @@ Package: x11-drivers/xf86-video-virtualbox-3.2.8#2.6.35-sabayon branch: 5, [__system__]

I have incorporated your suggestion, Thompson, along with the filters I mentioned above. Thanks for taking the time to comment.
BTW, if you want to edit the article and make the examples consistent (they are for a hotchpotch of kernel versions at the moment) then please feel free. You might want to update the examples to cover e.g. originally-installed kernel is 2.6.35 and kernel to be installed is 2.6.36.
