Some paths seem to be set during the configuration or the build but others are hard-coded. Can you please make the paths (/usr/dt, /var/dt, /etc/dt) configurable through a central configuration file? Storing all arch-independend files inside /usr/share and all the arch-dependend stuff in /usr/{bin,sbin,lib,libexec} would also be appreachiated, but that's probably a bit too much to change for now.
A goal, but will take time.
The main directories (/usr/dt, /var/dt, /etc/dt) are already handled via defines in config/cf/cde.rules that can be redefined in an OS specific .cf file.
More specilized divisions, like /usr /share and the like need to be done once the autotools branch is done and merged.
Closed as the majority of this was completed some time ago.
