[gentoo-user] kernel make files disappear

[gentoo-user] kernel make files disappear

[Daniel Hilst Selli]

I have some old kernel trees here.. But there is no Makefiles for
some of them. I did not remove the Makefiles. There is anyone
having the same problem? Whats happen?

I emerge -NuD periodically, some times I see my kernel
being updated.. May portage remove my Makefiles??

In real life, portage seldom (if ever) *updates* a kernel src package. 
Almost all kernel versions, even ones with teeny-weeny -r changes in 
the version number, are an entirely new package which installs into 
it's own directory in /usr/src/

So, 
gentoo-sources-2.6.39-r1 
will touch nothing belonging to 
gentoo-sources-2.6.39

This is in contrast to how most packages work, where -r versions 
contain gentoo patches or ebuild tweaks but still use exactly the same 
sources.

Perhaps you have unmerged old kernel sources that were previously 
built. In this case portage will remove the files it put there and 
leave everything the compiler built. Run this:

du -sh /usr/src/*

Anything with a size of about 300M has probably had this happen. 
Intact trees that were built tend to come out at around 700M

Thanks for replying, so this might be the case
output -> http://sprunge.us/YMAM

Can this be done after a emerge --depclean, while booted on some newly 
emerged kernel?

Please don't use images on websites like that for command output, 
rather just copy the text from your console into the body of the mail.

--depclean is unlikely to do that as kernel sources almost always end 
up in world. It will behave different if you emerge the sources with -1

The running kernel has nothing to do with what portage may or may not 
do with your installed sources, much like how KDE will still run fine 
regardless of whether you have the tarballs downloaded or not, or 
whether you have KDE source trees lying around or not.

I don't know what the answer to your question is, your statements are 
vague and only apply to principles but you want specifics. You are 
going to have to look inside those directories and see what is there, 
because I can't.

I was curious, and I looked at it...that's not an image bin, that's a
post-from-terminal pastebin. But, yeah, something like that is
better-done inline in an email.

Actually, emerge --depclean will remove old kernels. At least, it does that on 
my machine.

I do, however, install with:
" emerge gentoo-sources "
This leads to "sys-kernel/gentoo-sources" to be entered into the world-file. 
Older versions will, as there is no version specified, be selected for removal 
by " emerge --depclean "

To avoid this, the used versions need to be seperately specified.
