Can you answer the following question:
Given a volume label, how does one figure out where the
corresponding
volume has been mounted into the Cygwin namespace?
We're not mounting volumes, we're mounting Win32 paths.
There is no direct correspondence between volumes and Cygwin
mount points.
When a person inserts removable media (USB memory stick, optical disk, ...),
Windows assigns a more-or-less random drive letter.
Cygwin automatically makes this drive letter available
under /cygdrive/ (or whatever the user has renamed /cygdrive to).
Given a (unique) volume label or disk UUID, blk_id(8) on
both Linux and Cygwin tells you the disk and partition
in /dev/sdXY format.
It does? Interesting. Where does it get the data under Cygwin?
In Linux, you can look up the mount point for device /dev/sdXY
in /proc/mounts or in the output of mount(8). Thus, given
a volume label, you can figure out where to access the files
on the volume.
How do you do that in Cygwin?
ls /cygdrive. Insert the disk. ls /cygdrive again. There's a new
directory entry now.
Or, open the "Computer" Window on your desktop.
some times ago, someone (you?) modifies cygpath to handle /dev/sdXY paths.
however, it seems there is a problem somewhere ?
