Can upstart handle symbolic links to config files?
Upstart watches its configuration directories with inotify and reloads the configuration when any of the files change or a new file is added. Apparently this doesn't work for symlinks.
To manually update the configuration use
$ initctl reload-configuration
Upstart does not support symlinks because they might point to a file on a partition that is not loaded at boot time.
I have gotten around this in my own project by putting the conf files in /etc/init/myscripts and then binding that to a directory in my repository.
mount --bind /etc/init/myscripts ~/code/repo/initscripts.
Add this to /etc/fstab and the binding will be persistent:
/etc/init/myscripts /home/me/code/repo/initscripts none bind
This effectively gives you hard-linked directories. Upstart will treat the conf files as any other, because they are local to /etc/init. Your DVCS will also see them as local files in the repo, so it will also treat them as it would any other files stored there. Best of both worlds.
