hostname, username, timestamp, absolute path etc. are a nuisance if they
can't be turned off with -fno-ident, -frandom-seed, -DSTRIP_FBSDID, ar -D and
the like.
the question as to what compiler was used to compile the kernel is a bit of an
oxymoron, since the kernel is made up of many different modules, which get
compiled
either by different compilers, or different compiler flags.
Yes, but in practice this seldom happens. In Linux they also just print
one compiler identification string at bootup, basically the compiler
which the main Makefile used.
since the compiler does 'sign' the modules it compiles (and clang will/should
do it soon: http://llvm.org/bugs/show_bug.cgi?id=7292) some tool like
file(1) could be modified to provide it, or config -x (8) ...
Well, gcc does this, and you get all the .comment sections merged into
the final kernel executable, but identifying it from there is a bit
messy. A simple sysctl is just handier.
And regarding clang, I don't have the time to implement this very soon,
and I doubt it is very high on the bug priority list with upstream
either. They just branched for the 3.2 release, and they are much
busier squashing bugs now. :)
IMHO, the only meaningfull information added to uname was the svn/git(and
hopefully hg) rev. version.
AFAIK newvers.sh only handles svn and git.
