#   establish minimal network plumbing (for diskless and dataless)
#   mount /usr (if a separate file system)
#   set the system name
#   check the root (/) and /usr file systems
#   check and mount /var and /var/adm (if a separate file system)
#   mount pseudo file systems (/dev/fd)
#   if this is a reconfiguration boot, [re]build the device entries
#   check and mount other file systems to be mounted in single user mode
