Sébastien Szymanski c6bca8cef0 fs/ext2: Remove support for auto-calculation of rootfs size
Auto-calculation of the rootfs size cannot be done in a reliable way
as it depends on the host filesystem and is broken on non ext4 host
(see bugs [1] [2]). So let the user specify the size he wants for his
rootfs.

[Thomas: as suggested by Arnout, use 60 MB as the default size instead
of 64 MB.]
