The -X +option is very similar to -x, but also prevents Cygwin +from setting up commands and environment variables for a normal Windows +program, adding another small performance gain. The opposite of these +flags is the -E flag, which means that no files should be +marked as executable. + + +The -m option causes the mount utility +to output a series of commands that could recreate both user and system mount +points.

The mount utility +can be used to change this default automount prefix through the use of the +"--change-cygdrive-prefix" option.
