This is some minor fixes to commits2cac7f5f11and2a34db1bdb. * Make sure to alien'ate the new initramfs rpm package as well! The rpm package is build correctly, but alien isn't run on it to create the deb. * Before copying file from COPY_FILE_LIST, make sure the DESTDIR/dir exists. * Include /lib/udev/vdev_id file in the initrd. * Because the initrd needs to use '/sbin/modprobe' instead of 'modprobe', we need to use this in load_module() as well. * Make sure that load_module() can be used more globaly, instead of calling '/sbin/modprobe' all over the place. * Make sure that check_module_loaded() have a parameter - module to check.
