Hello Robert,

I wrote those instructions a long while ago, working on Tiger and
having a whole lot of TeX binaries lying around, most probably I also
did "chown myname" to the whole TeX tree before performing any
operation described there.

I have a "clean" system installed now, I'll try to review the
instructions, but if anyone else volunteers, please step forward.

But some important notes:
- You probably need to execute the rsync command as root, else you
cannot sync anything
- If you do rsync as root, the owner id is preserved, which is
probably not what you want (if anyone has a quick recipe, let me know;
there must be some trivial switch to change the behaviour of that)
- You can fix this by running "sudo chown -R root:wheel
/usr/local/texlive/2008" (but I don't know the difference between
root:wheel and root:staff) after you sync
- The instructions are about using rsync with current context. I'm not
sure if that version works with the latest LuaTeX (most probably not).
- There are some issues with LuaTeX binaries for Mac that will
hopefully be resolved soon, but one thing to note is that while Hans'
latest version most probably requires LuaTeX 0.37, Mac binaries still
contain LuaTeX 0.35 in the repository.

OK, and I noticed one rather important thing now. TeX Live binaries
like texexec are symbolic links to texexec.rb which is not executable
in the repository from where you sync. this is fixed in TeX Live
itself (I think), but not in the ConTeXt minimals repository.

I'm now trying to figure out which step makes problems in "permission denied".
