Fedora Core 15: /dev/mapper/vg_youwish-lv_swap swap swap defaults 0 0 tmpfs /tmp tmpfs defaults 0 0 Removed other options it should have, but defaults do not include nosuid,nodev,noexec.
You obviously customized the install or changed it post installation as this is not the default way it gets setup. Below is the filesystem setup when using all the default options (no customization): # df -hP Filesystem Size Used Avail Use% Mounted on rootfs 5.5G 2.1G 3.4G 39% / udev 495M 0 495M 0% /dev tmpfs 502M 272K 501M 1% /dev/shm tmpfs 502M 612K 501M 1% /run /dev/mapper/vg_fedora15test-lv_root 5.5G 2.1G 3.4G 39% / tmpfs 502M 0 502M 0% /sys/fs/cgroup tmpfs 502M 0 502M 0% /media /dev/sda1 485M 30M 430M 7% /boot /dev/mapper/vg_fedora15test-lv_root 5.5G 2.1G 3.4G 39% /tmp /dev/mapper/vg_fedora15test-lv_root 5.5G 2.1G 3.4G 39% /var/tmp /dev/mapper/vg_fedora15test-lv_root 5.5G 2.1G 3.4G 39% /home Despite what the above looks like, /tmp is actually part of the root filesystem. Yes, of course you can change your setup post install or if you're daring enough during the install, but that wasn't the point of the research. -- Mark S.
