Re: Portable Cygwin on a CD

I'm thinking "autorun".. don't know why (yet)..

If it's just for personal use, there are no licensing issues AFAIK.

This is where I start thinking "autorun"
Would it be possible (my guess is that it certainly would) to make an 
autorun.ini file that runs a simple Windows program (compiled, say, with 
the -mno-cygwin option) that
a. looks which drive it is on (in argv[0])
b. runs mount
c. runs rxvt

That would be fixed with the autorun :)

As your autorun won't need Cygwin (because you've compiled it with 
-mno-cygwin) your chicken-and-egg problem is gone :)

I *think* that is a question of the permissions you have in the registry - 
you'll need to use user mounts to take care of that (WAG)

Would make it look nicer, but I don't think it will change anything 

I'd be *really* interested if you get this working :)
