rAM диск инициализирован загрузчиком (boot loader initialized RAM disk)
Конфигурация (Configuration)
/dev/initrd is a read-only block device assigned major number 1
and minor number 250. Typically /dev/initrd is owned by
root:disk with mode 0400 (read access by root only). If the
Linux system does not have /dev/initrd already created, it can be
created with the following commands:
mknod -m 400 /dev/initrd b 1 250
chown root:disk /dev/initrd
Also, support for both "RAM disk" and "Initial RAM disk" (e.g.,
CONFIG_BLK_DEV_RAM=y and CONFIG_BLK_DEV_INITRD=y) must be
compiled directly into the Linux kernel to use /dev/initrd. When
using /dev/initrd, the RAM disk driver cannot be loaded as a
module.
