In no case?  In any command file?  Careful with those absolutes...  
While I understand your intent (and your statement is correct for what 
you intend), it's quite possible to mount system disks additional times 
for specific requirements, and there are constructs where mounting the 
disk (shared) is handy to state (and enforce) an interest in a 
particular disk.  Mounting a disk (shared) in a batch job means that 
the disk won't drop offline due to an operator request, a state which 
can be handy for data disks and for remote-mount system disks.  
Mounting a disk a second time (during the bootstrap) can also be common 
to bring that disk online in a cluster, too.  Now does everybody do 
this?  No.  (A number of folks probably don't know about mounting disks 
shared to maintain interest, but it's documented.)  And does the system 
manager generally need to deal with mounting the local system disk in a 
standalone configuration?  No.  But sites can choose to...
