What if we looked at the size of available swap rather than RAM? People don't really expect to have their actual memory eaten by something that appears to be a disk filesystem (and used to be one). I'd say that eating some of swap space would be less surprising.
In other words: a machine with 64MB RAM + swap will want to use tmpfs (much faster than a regular filesystem), but one with 1-2GB and no swap probably won't. -- 1KB // Microsoft corollary to Hanlon's razor: // Never attribute to stupidity what can be // adequately explained by malice. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
