| 28 | The run-init utility is used from initramfs to select a new |
| 29 | root device. Under initramfs, you have to use this instead of |
| 30 | pivot_root. |
| 31 | |
| 32 | Booting with initramfs extracts a gzipped cpio archive into rootfs |
| 33 | (which is a variant of ramfs/tmpfs). Because rootfs can't be moved |
| 34 | or unmounted, pivot_root will not work from initramfs. Instead, |
| 35 | run-init deletes everything out of rootfs (including itself), |
| 36 | does a mount --move that overmounts rootfs with the new root, and |
| 37 | then execs the specified init program. |
| 38 | |
| 39 | util-linux has a similar tool, switch-root. |
| 40 | run-init differs by also having a "-d CAPS_TO_DROP" option. |
