New Revision: 187246
URL: http://svn.freebsd.org/changeset/base/187246
Log:
Another change from Christoph:
replace the table of partition with a simpler and faster array of strings.
The change in the array is done mechanically, using vi commands.
Most entries in the table are probably 15+ years old and largely outdated,
so the next step is to remove stale entries with more current values.
Submitted by: Christoph Mallon, with small changes from me
