Servers with kernel built exactly with this script in production which
I have is 3 and one of friend of mine (not much load, just 3 VEs for
tests), this number going to increase twice soon. But in general I'm
using kernels build with make-kpkg since 2008 .

1 & 2 done - https://github.com/CoolCold/tools/commit/a5a56976fb84de9c6914072daa8daadad7d358bf

Not sure got your point about 3 - I'm considering that usage output as
some reference in general, not as exact values, that's why it contains
lines like:
  echo "-R <rhelid> - specifies rhel version id, now latest rhel is 6,
previous was 5."
to make people know - it may be such or other way. Turning back to
your suggestion I think I can print default values at the end, like:
  echo "-R <rhelid> - specifies rhel version id, now latest rhel is 6,
previous was 5. [Default is: ${KERNELINFO["rhelid"]} ]"
what do you think about this?
