$ search sys$system:setfilenomove.com file_name /window=(0,0)

gives the list below on V8.3 (I've taken out the extraneous stuff on 
each line to save clutter). It was done on an Alpha, but the inclusion 
of SYS$EFI.EXE suggests it's common with Itanium.

Note the EXEs in SYS$LDR

When I implemented DFO on on a whole bunch of systems, I wrote a command 
procedure which read setfilenomove.com to check the files concerned and 
set the NOMOVE attribute if possible (not possible for files open by VMS 
itself). This did save me quite a few reboots over the following years.

P.S. It's a pity that F$FILE_ATTRIBUTES can't access open files to 
return the MOVE attribute - I had to inspect those files manually with a 
DIR/FULL.
