on my system it is touching ksplash and randr stuff; font dpi forcing is 
there; language/locale defaults... all in all: it's user customizations.

even if that file is needed (and i'm rather doubtful it is on the sorts of 
devices we're targetting) we can generate it once or when the user changes the 
relevant settings. there should not be a need to do it on every log in.

agreed.

i'm guessing we'll probably have lots of small things to remove rather than 
any really big things. the people who went before us did a good job given the 
tasks they had. thing is, the task has changed :) 

for instance, calling kde4-config 5 times in the startkde script just to find 
out paths that we _know_ without question (and so can easily hardcode in 
without risk) is just wasteful for us. contrast with the desktop where these 
things are much more fluid and running kde4-config is a negligable cost.
 
hopefully such bootchart runs _will_ give us big targets to go after, but we 
shouldn't be surprised if it's just lots and lots of little ones that will 
require us to question the assumptions made for the desktop in our startup 
sequence.

also, if we don't have a runtime-configured read ahead set up on the image and 
the files that are most needed lined up nicely, we should also investigate 
that. it _really_ cuts down on runtime from what i'm seeing on the pandaboard.
