TMPFS is not usable without swap, it should have better algorithms to adjust it's size, depending on amount of memory/swap available. # swapoff -a # swapinfo Device 1K-blocks Used Avail Capacity # top Mem: 253M Active, 282M Inact, 933M Wired, 3972K Cache, 135M Buf, 491M Free Swap: # df -h /tmp Filesystem Size Used Avail Capacity Mounted on tmpfs 436k 436k 0B 100% /tmp no free space on /tmp # uname -a FreeBSD gpr.drweb.com 9.0-BETA2 FreeBSD 9.0-BETA2 #0 r225446M: Thu Sep 8 17:30:46 MSK 2011 gpr@gpr.drweb.com:/usr/obj/usr/src/freebsd-head/sys/DRW_A amd64 On Mon, Nov 07, 2011 at 04:21:50PM +0000, Marcel Moolenaar wrote: > Author: marcel > Date: Mon Nov 7 16:21:50 2011 > New Revision: 227310 > URL: http://svn.freebsd.org/changeset/base/227310 > > Log: > Don astbestos garment and remove the warning about TMPFS being experimental > -- highly experimental even.
