-===== What is this? ===== 
-An attempt to package as much as possible of the files of Fedora/switch. Could make deployment easier, replaying versions, rollbacks. 
  
-===== Simple packaging setup ===== 
-I use noarch for building.  One can build the rpms for example on Fedora/x86_64 or rhel7/x86_64 and later install them on switch/aarch64. Used a KVM guest with RHEL7 for the following.
