For illustration purposes, they are touched beforehand. We run an active storeio translator on the ramdisk file to give us 50MB of RAM to work with, and then we make an ext2 filesystem on it. A boot CD would presumably have a ready-made image to copy into the ramdisk, so we wouldn't really need to run mke2fs. After making sure the file system is writable, we mount the image with an ext2fs translator onto tmpfs. And now we're writing files on a writable file system that originated on a readonly filesystem.

We run an active storeio translator on the ramdisk file to give us 50MB of RAM to work with, and then we make an ext2 filesystem on it. At this point we'd could copy the contents of the /var directory into the tmpfs, and then symlink /var to /tmpfs/var. The same goes for all other mutable dirs. > > > -> > > [mail](http://lists.gnu.org/archive/html/bug-hurd/2000-12/msg00073.html) -> > > -> > > on bug-hurd, and it has some drawbacks. +> > > This approach of putting an entire ext2 filesystem in a copy zero'd store has some drawbacks listed [here](http://lists.gnu.org/archive/html/bug-hurd/2000-12/msg00073.html).
