#  NOTE:  When a change is made to the source file for

#
#  -	If an existing entry in minor_perm is having its
#	attributes e.g. permissions, ownership changed,
#	add it to the list produced by make_chattr_list below.
#
#  -	If an existing entry must be deleted, add it to

#
#  -	If a new entry must be added to the file, add it to the
#	list produced by make_add_list.
#
#  -	If a new entry is being added to minor_perm, but there
#	may already be devices of that name on the system (e.g.
#	we used the system default permissions in a previous release),
#	and those old devices now need to have their attributes changed,
#	add it to the make_chattr_list AND the make_add_list lists
#

#
#  If an entry in /etc/minor_perm needs to have its attributes
#  changed, identify the entry in the list copied to /etc/chattr.$$

#					      devices whose attributes
#					      will need to be changed>
