SubjectRe: ELF - are .comment and .note sections needed? Inline syscalls?

I usually delete all .note and .comment sections from installed
binaries (including shared libraries) and I didn't have any problems
yet. It just saves me a couple of MBytes :)

You could also strip off the symbol table of your shared libraries - if
there weren't some braindead software configuration scripts out there
that read it in order to find out which functions are present...
