Doh, someone tell me to RTFM... ;)
I still don't think that it should ever be implemented. If you've got home dirs on an almost-full disk (i.e., like 99%), you could conceivably be ``wasting'' maybe 5, 10, even 20% on undeleted files, and the full disk would become a needless annoyance (IMHO :). Does someone have stats on how often & what size files are deleted/created/modeified in a home directory structure? Almost sounds like a computer science master's thesis topic to me.. ;)
