Ok, Darren. But if we compress a compressed file, size may even increase 1% or 2%. What I wanted to say is, that not much, if anything, compares to clofi plus iso9660 layout optimizations. If we would be talking about thousands of shell scripts, then maybe we should reconsider. But all you would save in _total_ would be the 1MB from /lib/svc/method. Compiling shell scripts is limited to exactly that. While the other approaches is universally employable. On the day when the kernel and userland migrates to shell scripts, then I give you a strong +1 ;-) But seriously, using gcc instead of Studio: That's really it! No changed interfaces, packaging nor anything else required. Requirements are limited to: 0.) Changing the nightly build env in order to make /usr/sfw/bin/gcc the primary compiler and SUNWspro the shadow compiler (see http://opensolaris.org/os/community/on/flag-days/pages/2006033001/). 1.) Afterwards debug the kernel, because normally the gcc object code is being discarded, and it is not linked. This kept at least one major kernel panic on IA32 undetected. Alexander Eremin (and myself in 2006, there you see that nobody detected it in 3 years! It was my fault, because I should have filed the bug in July 2006. Alexander did it now. Must look-up bugid. Not sure what the current status is. This only affects the 32bit x86 kernel, none else). Additional space-optimization flags might degrade performance. Everything has its price. Ok, so you would not specify any. But even then you would save 20% (or so, it depends) space consumption. Please somebody: Keep an eye on it!
