26 There's a furious debate going on in -dev about this very thing, and
27 the bottom line is that your statements above are way too simplistic.
29 - there is no guarantee that /proc/config.gz represents the kernel the
30 binary will actually run on (this emerge might well be the last
31 process you ever run on that kernel)
32 - there is no guarantee that /usr/src/linux corresponds to anything at
33 all (it's a symlink and can point to anything, even invalid stuff)
34 - there is no guarantee that the build host will run the code (think
35 build farms, crossdev etc, so every available config cannot possibly
36 be valid)
37 - and a couple more
39 Basically, the only thing left for the ebuild devs is to notify the
40 user with the important information.
42 The question is not whether to halt the build or not (that cannot and
43 will not be done) but how to do the communication:
45 - news item
46 - elog
48 - some arb notice on a web site somewhere
49 .....
51 This is gentoo, the distro that does not hold your hand and gives you
52 every opportunity to keep both pieces. This is a good example of such.
