I forgot to say that this will no longer be true when we (eventually)
introduce the top-level parallel build, because, as Arnout already said,
each package will install in its own, private copy of TARGET_DIR, not
only that, but also its private STAGING_DIR and HOST_DIR as well.
One thing that Arnout suggested, is to (mostly) get rid of TARGET_DIR,
in favour of a package-prefix FOO_TARGET_DIR (amd similarly for
filesystems).
However I still don't think that is a good idea, because that would
allow packages to easily find and write into another package's
TARGET_DIR. Using a single TARGET_DIR, instead, will make it harder
(but not impossible, agreed).
Ditto filesystems.
So I believe we still want to keep a context-specific TARGET_DIR. It is
easier to use, it is more stable, we can update it at will, and it makes
it harder for packages and filesystems to do weird stuff.
Regards,
Yann E. MORIN.
