scripts and settings. Most are added to the package -- the files CHANGED for Absolute are:

/etc/group.new  -- removes haldaemon and sddm, adds storage
/etc/profile.new  -- pulls mail check and changes prompt
/etc/passwd.new    - removes haldaemon and sddm

/install/doinst.sh  -- pulls check for haldaemon and sddm

added specifically to the /etc folder:
/etc/sysctl.conf
/etc/absolute_version
