Bug#823400: tmpfs size calculation fails

[Marcos Mello]

It is 2.4.5-23-amd64 unmodified. I just customize the boot media (bootloader and
filesystem.squashfs path). "To RAM" (toram=filesystem.squashfs) works, but the
errors are still shown. Boot with live-boot.debug and take a look at
/var/log/live/boot.log.
