Summary

We've always used 999 as a kind of special super development version. Right now when a vyos-1x package is build from the current branch it's named like: vyos-1x_1.5dev0-3578-g2f1d1d343_all.deb
marking the 3578th commit after tag 1.5dev0 was created ad some random point in time. The current Git repo commit id is 2f1d1d343.

To clearly unbind this from the 1.4, 1.5 and rolling development branch the naming scheme of the package should be changed to: vyos-1x_999.0-g20a4de757_amd64.deb marking it a development package build from Git (g) from commit 20a4de757
