basically:

strace -e trace=open executabletobetraced 2> executable.log

then I apply a mix of grep/cut/sort to get a list of files being opened,
something like:

grep RDONLY | grep -v DIRECTORY | grep "^open" | grep -v "such file" |
cut -c7- | \
 cut -d"\"" -f1  | sort -u | grep -v "^/home/" | grep -v "^/proc/" | \
grep -v "^/tmp/" | grep -v "^/dev" 

(I think it could be simpler that that)

if you plan to strace X, I recommend you to go to runlevel 3 and do it
from there
