It would be useful if there were a mechanism to provide the system with additional (arbitrary) objects at boot and expose them via the filesystem interface. There are at least three general use cases:
1. Alternate kernel modules/configuration files. This would be useful mainly for development but would also allow customers who wish to use non-illumos drivers a means to provide them outside the platform.
2. Persistent FMA state to allow the kernel to retire faulty devices prior to most of the boot process.
3. Anonymous DTrace enablings.
