Re: Shrinking NetBSD - deep final distribution re-linker

Sorry for quite confusing subject, just i don't know how exactly express my
ideas :) Not sure where exactly should i post this message..

tech-embed is definitely the place for this type of discussion.

it sounds like you are describing crunchgen. man crunchgen, and take a look at src/distrib/i386/floppies/ramdisk-big/list for an example. crunchgen does have limitations and caveats (which i can enumerate upon request) but all can be worked around in one way or another. and there is an advantage of sharing all common code pages w/o ld glue. :^)

best regards,

Does crunchgen remove unused portions of the code, though? I thought it simply linked all the programs into one file. In which case all of libc's extra baggage would come along with it.

crunchgen does not remove unused code, but the linker does. :^)
