Why is it a good idea to mount /tmp and some var dirs on memory disks: root@raspberry-pi:/usr/ports # df -m Filesystem 1M-blocks Used Avail Capacity Mounted on /dev/mmcsd0s2a 14694 777 12742 6% / devfs 0 0 0 100% /dev /dev/mmcsd0s1 16 3 13 20% /boot/msdos /dev/md0 28 4 22 16% /tmp /dev/md1 14 0 12 0% /var/log /dev/md2 4 0 4 0% /var/tmp root@raspberry-pi:/usr/ports # Is this about speed or power, or maybe space? Can I not put all these dirs on sd card? I'm new to arm, so maybe things are different to other arches. Thanks Anton
