==== Local Packages ====

Made some significant changes to my buildsystem:

 * Used suggestions from FedoraProject:Extras/MockTricks to enable the autocache of `mock` buildroots to speed up mock. It's interesting to see how much the size of the minimal buildroot (the packages listed at fedoraProject:Packaging/Guidelines#Exceptions plus their dependencies) changes between distributions:
 {{{

 * Also from FedoraProject:Extras/MockTricks, I set up a local `squid` cache. This isn't needed for any of the current distribution releases I'm building for since I keep local mirrors of those, but it enables me to build packages for rawhide without having to constantly re-download lots of large packages.
 * I made myself a wrapper script (`mb`) to run `mock`, so as to ensure that I don't forget to use the `--autocache` option or use `setarch i386` for 32-bit builds. It also gives me a shorthand notation for the distributions, so I can do:
 {{{
$ mb fc4.32 some.src.rpm
$ mb fc4.64 some.src.rpm}}}
 . and I'll get 32 and 64 bit builds for FC4 :-)
 . Here's the script in  case it's of any use to anyone (it'll need tweaking):
 {{{
#!/bin/bash

# mb: mock build
# mb distro.archbits options ...
#
# e.g.
# mb rhl7.32 rebuild some.rpm
# mb fc5.64 rebuild some.rpm

usage () {
        echo "mb: usage: mb distro.archbits options ..."
}

if [ "${distro}.${archbits}" != "$root" ]; then
        echo "mb: cannot parse distro.archbits: $root" 1>&2
        exit 1

# Only valid values for archbits are 32 and 64

 * Updated `buildsys-macros` to use the next major release version if the release version number extracted from `/etc/redhat-release` has a number larger than 80 after a decimal point. So for instance, building it on the current rawhide (FC 5.91) returns:
 {{{
dist .fc6
fedora 6}}}
