 I understand your concern about G_ELI.  I'm not a fan of  
 root_mount_hold, and I'd really like it to go away in favor of the  
 SYSINIT and INTRHOOK mechanisms that already existed before  
 root_mount_hold was introduced.  It's really a hack, and a messy one  
 that requires extensive modification to the system to work; i.e.  
 root_mount_hold calls need to be added to just about every storage  
 driver, not just 'ad' and 'da', while the existing SYSINIT based  
 ordering does not.
 
 I'll look into this and see if I can come up with an alternate solution.
