I have switched from jffs2 to ubifs. It buys you a second or so. Not
huge. I got a much bigger improvement from going through the /etc/rcS.d
and /etc/rc4.d (I switched from run level 5 to run level 4 to get rid of
the Xserver and other cruft that I didn't need). I went through each
script and thought "do I need this?" If not I just added an exit(0) at
the top of the file.
FYI Sakoman has a good page on ubifs
You also need to change a boot loader variable when you make this change.
I am also working on stripping down the kernel. I have not yet spent any
serious time with the config file but my cursory look leads me to believe
that we can definitely shrink it.
