speeding up boot time?

[Cliff Brake]

Hello,

I have a ARM device running a fairly heavy application with regards to
# of libraries (gtk, cario, gstreamer, etc).  Looking to speed up boot
time, there are several operations that take a long time:

- udev
- ldconfig
- actual application start

Has anyone had any success speeding up these operations and what
methods were used?  mdev is on the list, but has not been tried yet.
We've also observed that ldconfig is writing the cache to a volatile
location.  Has anyone thought through putting the cache in flash --
how much write activity is expected, etc?  Also, if ldconfig is not
run, then the app start time takes way longer so it is a net loss.

Thanks,
Cliff
