While beaker is awesome in how it gives you many ways to search the inventory based on specific requirements/groupings, sometimes you might want to mark a machine as part of some logical grouping that doesn't easily fit into the categories already available.
It would be great if you can tag machines with a particular tag, then be able to search all machines that have that tag. An example might be tagging a machine as "maybe_broken" that admins could search on to see what machines might be having issues, or tag a machine "used_by_ops, used_by_qe" to show machines that might be used by more than one group or used by abnormal people/purposes.
Likewise a machine may be in a group "gss" but you want to also tag it with the group "fujitsu" for all fujitsu machines etc.
Possibly needs to be thought through with regards to workflow as well to make sure we are not duplicating functionality already in beaker.
Bulk reassignment of issues as Bill has moved to another team.
Beaker 1.1 will likely include a System Pools feature that covers some aspects of this proposal (see http://beaker-project.org/dev/proposals/system-pools.html)
An arbitrary tagging capability beyond the System Pools proposal is not currently planned.
