It is theoretical possible to use the initramfs ramfs as root filesystem, but it has a big drawback. In the initramfs we create three dynamic tmpfs (a superset of ramfs) for root, tmp and log with an upper memory limit set, which can be defined in leaf.cfg. This means that, when correctly set, that growing files (like logfiles) can't crash the system if the total size is beyond the physical memory size of the system, because of the upper limit. This isn't possible with the simple initramfs fs. Eric ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
