just as a cautionary tale for the goal of moving everything to the dts: I am working with some basic infiniband tools. As part of their goal of making it all portable and easy to build, they use the libtool support tools. So, for a simple command line like this:
/bin/sh ./libtool --mode=link --tag=CC gcc -g -O2 -o src/vendstat src_vendstat-vendstat.o src_vendstat-ibdiag_common.o -lopensm -losmvendor -losmcomp -libmad -libmad -libumad -libcommon gcc -g -O2 -o src/vendstat src_vendstat-vendstat.o src_vendstat-ibdiag_common.o -lopensm -losmvendor -losmcomp -libmad -libumad -libcommon
They need the libtool script, which is wc libtool 7363 26779 212348 libtool
7363 lines. Geez, how long is the program?
The program is part of a set of diagnostic tools, and the bulk of them are about 200 lines long. So, for a 200-line, 5330 character program, we have a 332 character command line and, if that were not enough, a 7363-line, near quarter million character script.
This is a good example of the conservation of complexity. It is always possible, in the name of hiding details, to create a monstrously complex system that no one can understand.
Just FYI.
