Rainbow may fail for a variety of reasons in such an environment. + +Thoughts: + + Rainbow opens or creates a variety of files both during startup and during + activity launch. These files include: + + - the /var/log/rainbow log file. + - the /var/run/rainbow.pid pid file. + - the activity log files + - the various spool entries associated with an activity launch + + It's probably safe to make the log files and the pidfile optional. For the + time being, I'm going to ignore errors that occur while they are created on + the theory that doing does not presently compromise any security goals and is + simple. + + The downside that I presently see is that I'm less likely to learn that an + environment exists in which Rainbow was unable to open the files described + above. + + Another downside is that our security goals might change in the future in + ways that invalidate the theories described above. + |
