FreeBSD-11.0-BETA1-amd64-disc1.iso is too big for my 700MB CD-r

[Maxim Sobolev]

You don't need that much for OS really if you compress the underlying FS
(be that ISO9660 or UFS) with the mkuzip. Just as an extreme example of
that, we have liveCD-type image that deals with provisioning a new systems
and troubleshooting issues on around 40MB ISO. That includes nearly all of
the stock base system tools (modulo compilers and other dev related bits,
fully linked ones, not crunch), full amd64 kernel (compressed separately)
and complete python 2.7 environment along with necessary dependencies. So
if your live OS takes 300MB+, it will be compressed down to under 100MB by
just using GEOM_UZIP.

Whatever people say here about moving to USB, ISOs are quite useful for
setting up VMs as well as for remove booting off IP KVMs.

JFYI.

P.S. It would be cool to have a loader that can read off CLOOP partition,
but it's just in my wet dreams now.
