And how is a random user supposed to know this? So if things start
acting up the answer is to add more swap and mess with fstab? WTF? So
now any software which uses /tmp for *gasp* temporary space is now
potentially broken depending on the size of the temporary data.
Sorry guys, this feature sucks. The rationale was and is handwavy at
best and none of the legitimate concerns which have been raised have
been answered in any meaningful fashion. There have never been any
numbers showing the IO/power benefit claims are true.
