Rawhide is a development distribution. DejaVu is updated often in rawhide because:
- its upstream is very dynamic (many releases with lots of additions needing testing)
- the Fedora package innards have heavily changed over time (not that easy to plug in a
default font dynamically)
- it's highly user-visible, and discovering some of those changes broke the system default
font on some systems a month before release time is not acceptable
- I like it that way :p
It's not updated often in Rawhide because users "need" it updated often, it's updated often
because there is a lot of development on this package and rawhide is there to track this kind
of changes and detect regressions early. The dynamics of a development distro are not the same
as those of a stable version.
