ah, i understand.
but there is a granularity problem i think. With modules we 'waste' about
2K per module due to 4K page sizes. (every module has to have it's own set
of pages). With 183 syscalls we'd waste much more 'partial pages', about
183*2K=366K resident memory, brrr.
A bit radical, but why not make /sbin/init a shell script which does
strace -f -o /tmp/sclog -c -S calls /sbin/init.real
The only problem is to get / mounted rw at boot time.
The above is real dangerous, you'll be in single user mode a lot
getting it to work the first few times, boot command line args like
init=/bin/sh are your friend ;-)
