I see your point. Has anyone created a distribution for a Flash Drive? Has

have seen a couple older posts talking about compressed executables (upx I
think), but no follow-ups.
I use the following bat files to set up the required Cygwin mounts.
The bat files must exist in a directory which contains a Cygwin
installation under cygwin. For example, the set up could be:
Flash drive as F:
F:\install.bat - Set up user Cygwin mounts, backing up any existing mounts
F:\uninstall.bat - Remove Cygwin mounts and restore previous mounts
F:\run.bat - Run bash
F:\cygwin - Cygwin installation
The bat files do not assume any specific drive letter.
I have the install script set up to mount the directory containing the
scripts as /home/user, then run.bat sets HOME to /home/user. The
user's Windows TEMP folder is mounted as /tmp, to reduce writes the
flash drive.
I had to rename the .bat files to .txt to get Gmail to accept them as
attachments.
