remove the whole disc treei structure. This allows one to specify the
disc trees created by a prior release build (under R/cdrom) as the
destination without destroying the contents. This better integrates
with release building and makes further automation easier.
MFC after: 2 days
The new system tries to be more automated so that there is less work for
the re's to do. It also no longer uses a /usr/ports tree as its input,
but uses the generated package build including its INDEX file as its input.
It parses the INDEX file, determines which packages should go on which ISO
images, and then builds full-fledged trees of packages that can be added
as an argument to mkisofs along with the tree built by 'make release' to
build a full CD image. The INDEX files in the populated trees are
generated with volume media number to make use of sysinstall's multiple
volume support so that the user is kindly prompted to insert the
appropriate disc for a package if it is not on the current disc. There is
still some more tweaking to be done here, but this part needs to be
committed. This stuff will all be used to prep the 5.4 release as well.
