It sounds like a good idea to me.  I found the current values being used in
a few places.

newlib/libc/sys/linux/fstab.c
   Just passing the value through.

newlib/libc/sys/linux/mntent_r.c
   Extracting the value from a string.
   I'm not sure where the string is created, possibly path.cc.

winsup/cygwin/path.cc
   Converts bits in flags to string ("user" or "system").

winsup/utils/cygcheck.cc
   Prints whatever it finds in mnt->mnt_type.

winsup/utils/mount.cc
   Uses current values of mnt_type several places.

winsup/utils/path.cc
   Converts m->issys to string ("user" or "system").

winsup/utils/umount.cc
   Tests p->mnt_type for current values.

It looks like the main confusion would come from people parsing the output
from cygcheck or mount and expecting the current values of "user" or
"system".
