FYI: The mounts on a Fedora Core 4 system:
/dev/hda2 on / type ext3 (rw) /dev/proc on /proc type proc (rw) /dev/sys on /sys type sysfs (rw) /dev/devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/hda1 on /boot type ext3 (rw) /dev/shm on /dev/shm type tmpfs (rw) /dev/hdb1 on /home type ext3 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) none on /var/named/chroot/proc type proc (rw) automount(pid1716) on /misc type autofs (rw,fd=4,pgrp=1716,minproto=2,maxproto=4) automount(pid1759) on /net type autofs (rw,fd=4,pgrp=1759,minproto=2,maxproto=4) nfsd on /proc/fs/nfsd type nfsd (rw) /tmp is nothing special (it inherits / which is ext3), but /dev/shm is a tmpfs mount which is world writeable and has the sticky bit set. The mounts on the x86-64 PLD system I've been borrowing (and on which I do not have root access): /dev/sda3 on / type jfs (rw) none on /proc type proc (rw,gid=17) sysfs on /sys type sysfs (rw) selinuxfs on /selinux type selinuxfs (rw) /dev/sda1 on /boot type ext2 (rw) /dev/sda5 on /usr type jfs (rw) /dev/sda6 on /var type jfs (rw) /dev/sda7 on /tmp type jfs (rw) /dev/sda8 on /home type jfs (rw) /dev/sda9 on /srv type jfs (rw) none on /dev/pts type devpts (rw,gid=5,mode=620) /root/pldcd-0.95.iso on /root/pld type iso9660 (rw,loop=/dev/loop0) /tmp is an explicit scsi mount. /dev/shm inherits / (which is jfs), but that's moot because the directory is not world writeable. The shell servers from sourceforge: /dev/md0 on / type ext3 (rw,errors=remount-ro) none on /proc type proc (rw) none on /dev/pts type devpts (rw,gid=5,mode=620) usbfs on /proc/bus/usb type usbfs (rw) /dev/md1 on /tmp type ext3 (rw) /dev/md2 on /var type ext3 (rw) /dev/md3 on /usr type ext3 (rw) /dev/md4 on /var/local type ext3 (rw) none on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) pr-fs-users-a:/home/users/a on /home/users/a type nfs (rw,nosuid,nodev,nfsvers=3,udp,rsize=16384,wsize=16384,hard,intr,addr=10.5.1.153) ... and so on [about 8 gazillion more /home/users/blah mounts trimmed]. Again, /tmp is not tmpfs (it's ext3 on a raid), but /dev/shm is a tmpfs mount which is world writeable and has the sticky bit set. And I reiterate that on my ubuntu laptop /tmp is not tmpfs (it inherits my ext3 /) but /dev/shm is a world writeable tmpfs mount that has the sticky bit set. My conclusion from this is that /dev/shm is probably a better default than /tmp for User Mode Linux's physical memory file, perhaps with a fallback to /tmp if it can't write there. But I'd appreciate hearing from other people with different systems. The assumption that tmpfs is already mounted on /tmp does not seem to be true on any preexisting system I can currently find out in the field. Where have you seen this?
