openmosixview bugs/issues/wishlist

Our local Debian group recently set up an openMosix cluster, and we are
using openMosixview as our visualization (i.e. show off) tool.  While
setting up openMosixview, we have identified some bugs, and wishlist
items.  I am also willing to help out with any of these issues if
needed.

- openmosixcollector should not store its statistics in /tmp.  From the
  FHS, the best place I can see for the stats would be
  /var/lib/openmosixview.  (Our local version of openmosixcollector has
  been changed to store the stats in /var/lib/openmosixview.)

- openmosixcollector should be able to automatically delete old (e.g. >
  7 days old) statistics.  (Alternately, this could be handled by a
  cron script.)

- openmosixcollector should run as its own separate user instead of as
  root (if possible -- I'm new to openMosix, so I don't know if it will
  be able to collect the statistics if it's not root).

- openmosixcollector should not output debugging info to stdout
  (especially when in daemon mode).  If it needs to print out debugging
  info, that should be sent to syslog.

- openmosixview should not use a hardcoded /tmp/nodes.tmp filename.  At
  least it should use a mkstemp(3)-generated file.  Ideally it should
  fork the external process with a redirected stdout, and read straight
  from the process.

- when generating the date string in openmosixcollector, should add 1
  to the month, since tm_mon is 0-based, but human-readable formats are
  usually 1-based.

- in most of the files, there are a lot of instances of things like
    "returndate = returndate + ..."
  where returndate is a string.  It is much better to write
    "returndate += ..."
  since this should, in general, be faster.

That's it for now.  I'm planning on looking through most of the code
later on, and I'll keep you informed of anything else I find.
