Yes, you should set that to "false". Basically, Tracker is designed
to index all the files in your home directory (think "Spotlight" on OS
X). However, in AFS, Tracker holds vcache entries open in the AFS
cache, and eventually AFS runs out of them, and anything you try to do
in AFS will fail. There is a patch to dynamically allocate the vcache
entries, but it's not yet in the upstream source. We considered
applying this patch ourselves, but since this would only affect a
small number of users (people who had logged into Debathena on earlier
releases of Ubuntu, we decided against it. We are planning to
implement a warning dialog at login time for people who have this
option configured.
New Debathena users will not see this, since Tracker was annoying
enough that Ubuntu disabled it by default in Intrepid.
