New Revision: 245700
URL: http://svnweb.freebsd.org/changeset/base/245700
Log:
Add a simple scripted partitioner. Documentation and more scripting support
will come soon. This lets the install process have a line like:
bsdinstall scriptedpart 'ada0 GPT {1.5G freebsd-ufs /, 10G freebsd-swap,
auto freebsd-ufs /usr}'
to set up a system with a 1.5GB /, some swap space, and a /usr using the
rest of ada0.
MFC after: 1 month
