I have applied a preliminary patch to Cygwin which allows to load the
mount entries from /etc/fstab and /etc/fstab.<usersid>. If none of
these files is available, the DLL falls back to reading the mount points
from the registry.
This allows to install a 1.7 Cygwin tree which is independent from a
parallel 1.5.x installation in terms of mount points. It's still not a
good idea to *run* two parallel DLLs, though.
Cygwin finds the fstab files by fetching it's own Win32 path and then
replacing the last two path components with etc/fstab or
etc/fstab.<usersid>, like this:
Get own path ==> C:\\cygwin\\bin\\cygwin1.dll
Where's fstab? ==> C:\\cygwin\\etc\\fstab
The layout of the fstab file follows the Linux layout. As example,
these are my fstab files:
$ cat /etc/fstab
C:\cygwin / ntfs binary 0 0
C:\cygwin\bin /usr/bin ntfs binary 0 0
C:\cygwin\lib /usr/lib ntfs binary 0 0
C:\cygwin\usr\X11R6\lib\X11\fonts /usr/X11R6/lib/X11/fonts ntfs binary 0 0
\\fs01\archiv /home/archiv smbfs binary 0 0
cygdrive /mnt auto binary 0 0
$ cat /etc/fstab.S-1-5-21-1220945662-261903793-725345543-1003
C:\cygwin\home\corinna\textmode-dir /home/corinna/textmode-dir ntfs text 0 0
c:\cygwin\home\corinna\managed /home/corinna/managed ntfs binary,managed 0 0
