I answer to everyone in the same post, sorry I there's no names with each quote..

You misunderstood what I wrote. I meant using Windows search utilities without entering Cygwin shell. The search does slow down when it goes through \cygwin folder. It's getting far worse when you're looking for a string in files on the drive (again, via Windows tools). I would just give it up.

My last installation was far from being complete, but did include X and lots of other things I needed or installed/compiled myself later on.

I was doing it via Total Commander. Yes, it did have a progress bar, so what? It took me 3 or 4 hours to have everything deleted (on Win98), believe it or not. I'm sure any other Windows tool would have given closer result. Dealing with Cygwin on Win2x/XP didn't show a big difference, although I've never deleted it completely when re-installing the system, just formatted the drive.
>As would mounting and/or deleting a separate Windows partition, no?
No, because the virtual Cygwin partition would be one Windows file. One file is much easier to delete than the whole C: drive, isn't it?

Sorry, I don't quite capture your point. I needed to delete Cygwin on my computer, period.

It would be a good thing indeed but who would create a new partition just for the sake of Cywgin only?

Be careful with what you write! I meant "to put files into a virtual filesystem", not partition in the Windows terms. You suggest C:\cygwin and instead of the big folder C:\cygwin\usr there will be one big file. When you run Cygwin, this file will be mounted as /usr folder. Have you ever mounted iso-images on Linux? It's absolutely the same principle. You mount it into a folder in f.ex. /mnt/iso directory and access its files as on normal filesystem (be it ro or rw).
>I have never had a cygwin install take hours. Minutes at best.
Same here, I nowhere wrote about Cygwin installation taking hours.
>No one on this list has vocalized such a plan AFAIK.
I'm glad to hear that, Larry, that's why I decided to post it here. This thought came to my mind more than one time while dealing with Cygwin (for 3-4 years).

Thanks, this is the only substantial reply to my post so far. I've never dealt with doing filesystems, so I'd rather leave it to someone else. But it seems to me that you're going a bit too far. The ordinary user wouldn't know it's a separate "partition" after it's mounted. There is mnt utility in cygwin already if I remember correctly. If you put all /usr into an iso image and mount it via mnt, it would be practically what I mean. The main minus here would be the speed of accessing files, but we can't talk about it until there's something to experiment with.
All the best,
