hmmmm...

Apparently I have much to learn regarding the relationship between the
kernel and the C library.  My assumption (mistake?) is that since the
kernel is written mostly in C that it must use the services of whatever
library /lib/libc.so points to.  Does it not, or does it simply
statically link all the relavant libc code?  Logically, I can see where
the kernel cannot rely on a dynamically linked library as it does many
things before the file systems are mounted.  Also, I can see that if the
kernel uses statically linked code in its C routines, that would allow
it to run on a glibc based system even if compiled on a libc5 based
system.  Have I guessed right?
