Note that last time I checked, there were still gotchas, perhaps the most annoying being the inability to loopback mount a file on tmpfs (ioctl: LOOP_SET_FD: Invalid argument). This caused tools like mkinitrd to break. One can hack around this by changing the tools to use another filesystem like /var/tmp, but it's just a hack. Since private namespaces are in 2.4.19pre, a much more sophisticated hack is to privately bind /var/tmp (or some other scratch space) on /tmp when loop devices are needed -- mkinitrd works, no source hacks required. These hacks of course don't work so well with ram-based systems though; in that case a ramdisk is still required. :-/ Regards, Bill Rugolsky.
