[Coco] NitrOS-9 EOU Beta 6 - what is VERM?

I have completed my pillaging of software and utilities from the EOU and
adding  them to my main NitrOS-9 "instance".  Now I'm getting into the
nitty gritty of how things work and are put together.  Today I'm working on
getting DriveWire working that way I want it to and adding some modules to
OS9Boot and removing others I do not care to use.  In this process I ran
across a module that is added to every one of the pre-built OS9Boot files
that I am not familiar with, VERM.  I searched through every single one of
the SCF modules and then all modules in /DD/MODULES/6809L2/MODULES/
structure.  I could not find a matching module with the same name or CRC
value.

Header for:  Verm
Module size: $0044    #68
Module CRC:  $20D19B (Good)
Hdr parity:  $B6
Edition:     $53      #83
Ty/La At/Rv: $F1 $80
Dev Dsc mod, 6809 obj, re-en, R/O

Helpful OS-9 tips:

In case some might think that looking at the ident information of so many
files is a chore, you can use the call command (which does not seem to be
present on the EOU) to ease this task considerably.

dir -s ! call ident -sv $ ! shell t -p

Searching all of the OS9Boot files for the presence of VERM is also just as
easy.

dir -s ! fgrep -i "os9boot" ! call ident -sv $ ! shell -p ! fgrep -i "verm"

Dir ed8 maintainers, it would be helpful if the -s switch also worked with
wildcards.
