Useful Solaris boot options

These can be added to Grub's "kernel" line on x86 platforms (or the equivalent ok prompt on SPARC):

Prevent a driver from being loaded:
    -B disable-[driver]=true

Boot in single user mode:
    -s

Display each SMF service as they're brought up:
    -m verbose

Load the kernel debugger (kmdb)
    -k

Verbose boot (for the most part, useless):
    -v

Boot without starting any SMF service:
    -m none
