Jigdo was created for the Debian community. The Debian Stable release
is known for its stability, i.e. slow change. Jigdo has its use in the
scheme of things. However, using it to stay current with a high churn
release such as Fedora is not one of them.

The ideal candidate for Jigdo is a slow changing distribution such as
CentOS, Debian, and Ubuntu LTS.  Even if you create a respin with a
package list that is a month old after an install there will be fewer
packages to update. This is especially beneficial when installing on
multiple machines or one that has a slow or limited access internet
connection.

By the way, when Fedora Unity Project first used Jigdo Fedora Core was
a relatively slow changing distribution.
