Well, I admit that I did not recall that, thanks. I also guess, without
actually reading, that your script has more thought put into it than
my quick hack, and of course will generally be better. However, my
own thing has a specific use yours doesn't specifically allow: If you
have few CDs with different ideas of where to put RPMs, and you still
want the convinience of having them all in the same dir, and exact
"union mount" will be less good.
And, BTW: Does anyone follow any progress on real union mounts for
Linux? A quick google search shows that this has been discussed on
lkml several times in the past, with nothing getting generally accepted.
