[gentoo-user] re-extracting linux sources

[Maxim Wexler]

Hi group,

After my last -uvDN world and subsequent revdep-rebuild and emerge
--depclean I found the main Makefile under /usr/src/linux was missing.
I managed to extract it from the sources and copy it over only to find
that, naturally,  many other files were missing too. I gave up after
the third extraction/copy pass. Which leads to the following:

1) What is the approved method of re-populating that all-important
directory, just untar the sources back in or ?

2)How can I prevent this from happening again? The gentoo docs just
say, after the dust settles,  to do a revdep followed by depclean. Is
that what did the deed? This was my first world upgrade and I sure
don't want to go through this again, if I can prevent it.

1) just extract the stuff in /usr/src

2) it never happened to me so I don't know.

No.  You'll miss the patches that don't come in the tarball.  To install 
it again, emerge it again.  For example, for gentoo-sources-2.6.30-r7:

   emerge gentoo-sources:2.6.30-r7

emerge --depclean will never remove it again since you specified that 
the "2.6.30-r7" slot is always to be kept.

By doing what I described above :)  It well never be removed unless you do:

   emerge -C gentoo-sources:2.6.30-r7

I just re-emerge the gentoo-sources package (or whatever you use instead).
I make a point of saving a copy of the most recent version of my kernel
.config file, though, in case the real one gets deleted somehow.
