Spotlight on network volume

I mount user's network volumes like this: [code]/sbin/mount_smbfs -o nobrowse //emphomedir/staff$ /tmp/homedirs[/code] I have edited /Spotlight-V100/_rules.plist like this: [code] EXCLUDE INCLUDE /private/tmp/homedirs /tmp /private NOTE Specify paths to include or exclude, preceeding rules which targ et user-homes with ~/ [/code] Yet whenever I open a Finder window and try an run a query on the contents of, say, /tmp/homedirs/sketch/My Documents/ I get nothing. Spotlight doesn't even try. Any ideas of what's going on here?
