Mutt is having an issue when being run from cron. It hangs and consumes
mass quantities of CPU, this stacks as subsequent calls by cron (every
ten minutes in my case) also hang. I don't feel like spending hours upon
hours trying to debug mutt, so I have disabled it's usage for the
scraper.sh script since it is trivial to setup cronie to use msmtp.
The wrapped commands were not getting properly "unwrapped" when used with
strings. This was causing eval "$@" to try to run the first word word in the
unescaped string.
When the archiso is updated, usually the packages are no longer in the build
directories. This update adds the AZB_PACKAGE_BACKUP_DIR variable to allow
repo.sh to gather packages from the backup directory to add to
demz-repo-archiso.
