You're not even trying. if tmpfs is faster than (say) ext4, then anything which uses /tmp will obviously speed up. Can I provide a use case where this will matter? Not necessarily. But then, can you provide a use case where this will *not* matter?

The 5% overflow safety exists for two reasons: - to avoid excessive fragmentation (which is not relevant for tmpfs) - to allow you to clean up when the filesystem does fill up. For tmpfs, you do that with: mount -o remount,size=foo /tmp where 'foo' is some size or percentage that's larger than what the tmpfs is currently mounted with. Now you clean up, and you reset to what it was before. > > If you're going to post a thread summary, please do not filter out > > information you don't agree with.

Yes, but if you want to have any remote resemblance of objectivity, then what you do not do is filter out everything you don't agree with. -- The volume of a pizza of thickness a and radius z can be described by the following formula: pi zz a -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
