You can also use the user's SID rather than name (and the SID doesn't
change). Furthermore, the "username" in /etc/fstab.d/username is NOT,
necessarily, the *Windows* username. It's the *cygwin* username mapped
to the user's SID via /etc/passwd:
cygwin_username:unused:1000:513:Long Descriptive Name,U-MACHINE\Win32
User Name With
Spaces,S-1-5-21-NNNNNNNNNN-NNNNNNNNNN-NNNNNNNNNN-1000:/home/cygwin_username:/bin/bash
So, this account's SID is
S-1-5-21-NNNNNNNNNN-NNNNNNNNNN-NNNNNNNNNN-1000
The Win32 username is "Win32 User Name With Spaces" (on machine
"MACHINE"). You can change that username to whatever you want, but the
SID will remain constant. ('Course, each time you do that, you'll need
to regenerate your /etc/passwd).
The cygwin username is 'cygwin_username' -- and the user mount file is
/etc/fstab.d/cygwin_username
However -- I don't think you'll see much concern over supporting
"renaming" user accounts. Technically the username is, as you say,
subject to change. That doesn't mean it's a good idea, or that it
happens anywhere CLOSE to often.
