Re: [osol-discuss] When's source included?
If you build a distro and make the resulting binaries (an ISO image...)
available on a website, all you need to do is provide a compressed tar file
(or an ISO image of one) of the make cleand source tree you used - there
is no reason to make the source tree part of your binary ISO image
Since the source tree tar file will be large (and not very interesting as
time marches on), a better way is to provide a pointer to the same IllumOS
or Oracle or ... versioned mercurial repository that *you* started with and
make a gzipped file of just your diffs ('hg export' or 'hg merge' as
appropriate). An interested developer could then grab the common/unchanged
sources from the same place you did, apply your changes and build their own
copy.
The goal is to make it so that someone else could build on your changes in
the same way you built on the work of others.

Please shed more light on what it takes to make a distro legal. I'd
appreciate it. :)

John's right. Another note here: when I originally said you need to
make available source for everything covered by the CDDL, I wasn't
specific enough. What I should have said was you need to make
available all source for CDDL'd code *should someone ask for it*. In
plain English: you can distribute the binaries by themselves. However,
as part of the distro image, you should have a README or similar file
which says if you want the source for this stuff, get it here and
point to the various repos (which, as John indicated, can be a
combination of stuff you maintain and/or someone else maintains).

If I wanted to make a distro/respin, (and this is only out of sheer curiousity), would all the OpenSolaris source have to be downloaded with it, or would it only have to be anything built or modified upon? I've read what it says on programs--I'm hoping this doesn't mean to download code for the whole OS, if one were to do this! Honestly wondering. :) You need to make available the source to ANY binary you distribute, if that binary's source code was covered by the CDDL. Now, you *personally* don't have to provide the source code - for unmodified stuff, it's perfectly OK to point to another resource (say the OpenSolaris repo), and say: I build this binary using those sources. The only issue here is that if that other repository ever goes away, you have to find some other method (up to, and including, doing it yourself) to provide the source code. This is the same with all Open Source programs; regardless of whether you wrote or modified or merely built the program, if you distribute the binary, then you have to provide the source if asked. The mechanism by which you make the source available is up to you. -- Erik Trimble Java System Support Mailstop: usca22-123 Phone: x17195 Santa Clara, CA ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
