//config: The run-init utility is used from initramfs to select a new
|
|
//config: root device. Under initramfs, you have to use this instead of
|
|
//config: pivot_root.
|
|
//config:
|
|
//config: Booting with initramfs extracts a gzipped cpio archive into rootfs
|
|
//config: (which is a variant of ramfs/tmpfs). Because rootfs can't be moved
|
|
//config: or unmounted, pivot_root will not work from initramfs. Instead,
|
|
//config: run-init deletes everything out of rootfs (including itself),
|
|
//config: does a mount --move that overmounts rootfs with the new root, and
|
|
//config: then execs the specified init program.
|
|
//config:
|
|
//config: util-linux has a similar tool, switch-root.
|
|
//config: run-init differs by also having a "-d CAPS_TO_DROP" option.
