I would much more prefer to get prompted for the correct time, because
with a wrong time fsck fail due to the last fsck is in the future. But I
don't know how to do prompting in init scripts correctly.
And to guess if the hardware clock is wrong I think we can look at the
installation time of the module directory of the kernel.
/boot/vmlinux-$(uname -r) is possible, too.
I propose this patch:
--- /etc/init.d/hwclockfirst.sh 2009-04-18 01:03:46.000000000 +0200
+++ hwclockfirst.sh 2009-05-16 17:52:48.675695938 +0200
