Compiling these modules, which are loaded on nearly every PC, in the

Does the boot time decrease depending on the number of modules you
include in the kernel? Maybe it's just one or a few modules that make
up the bulk of that time.
to be tested. was just a rough guess of the most common modules,
compiled and measured.
Also should configuring these bits as external modules really have
this much of an impact on the boot time?
yep. nash, udev, rc.sysinit.. all wait on module loading
But 10s or 25% of boot time just for loading the modules? That sounds quite
bad. Maybe instead of moving the modules into the kernel it would be better
to find out why exactly the loading takes so long and to look at possible
optimizations.
