Updated the init script, now waits for pids

parent c465636a
v 6.3.0
- Init script now waits for pids to appear after (re)starting before reporting status (Rovanion Luckey)
v 6.2.0
- Public project pages are now visible to everyone (files, issues, wik, etc.)
THIS MEANS YOUR ISSUES AND WIKI FOR PUBLIC PROJECTS ARE PUBLICLY VISIBLE AFTER THE UPGRADE
