is in the install process being slow, not in how fast the media is.
And it uses the media in a way which is particularly bad for
DVDs.

We know of several ways to speed up install, and it will
happen.
We need to:
1) keep dvd spun up.
2) switch to lower cost compression instead of bzip2
3) stop rewriting /var/sadm/install/contents file repeatedly.
If we stored the packages as a single CPIO archive instead
of separate files on the dvd, we could stream the data off
continuously, uncompress it and install it all at the same
time.
What about just storing them as stream format packages and adding
support to libpkg to do the decompress on the fly ? Would that help?
One of the other advantages of stream format packages, well from a
security geeks view of the world anyway, is that they can be
cryptographically signed and are automatically verified against
configurable trust anchors when they are installed with pkgadd.
