In order to achieve this, root filesystem mount is moved from SI_ORDER_FIRST to SI_ORDER_SECOND in the SI_SUB_MOUNT_ROOT sysinit group. Now, modules which wish to usurp the default root mount can use SI_ORDER_FIRST. A compiled-in or preloaded MFS filesystem will become the root filesystem unless the vfs.root.mountfrom environment variable refers to a valid bootable device. This will normally only be the case when the kernel and MFS image have been loaded from a disk which has a valid /etc/fstab file. In this case, the variable should be manually overridden in the loader, or the kernel booted with -a. In either case "mfs:" should be supplied as the new value. Also fix a typo in one DFLTROOT case that would not have compiled. |
