I'm working on a script which will survey the various build options (NO_FOO, NO_BAR etc) and what their impact is on the installed system footprint. http://phk.freebsd.dk/misc/kernel_options/HTML/ The table shows size of the total installworld image, including the GENERIC kernel. Delta is the number of blocks compared to a full installworld, and no, I'm not quite sure yet why some of them take more space. Number of extra files and number of eliminated files (these link to a "mtree -f -f" output file so you can see which they were. When done chewing, all the options will be tested for their effect during "installworld only", "buildworld only" and "build+installworld" usage. When completed, this script will end up under src/tools/tools Poul-Henning PS: Interestingly, this survey has theological implications as well as it proves the long held belief that C++ is evil: The NO_CXX option which prevents the installation of this evilness eliminates exactly 666 files :-) -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
