• update.sh (location doesn't matter, but $BASEDIR will do):
  • $BASEDIR: directory containing config and meta data for repo
  • $OUTDIR: contains public http repo data
  • add to crontab
• $BASEDIR/conf/options
  • replace $keyshortfp with your private keys short fingerprint
  • basedir and outdir from $BASEDIR and $OUTDIR
• $BASEDIR/conf/distributions
