Bugzilla Bug 56432

slocate's PRUNEFS variable already contains supermount.

subfs is another system for automatically mounting and unmounting removable media drives, similar to supermount. (subfs is provided by sys-fs/submount)

Therefor I think PRUNEFS should not only include supermount,
but subfs too.

Oops, changing the component to core system as it is a sys package.
