[darcs-devel] [issue1753] darcs: opening of '_darcs/index' failed: does not exist (No such file or directory)

Eric Kow <kowey at darcs.net> added the comment:

We need to focus on getting this resolved from a user point of view.

Let's narrow down to what happens when you have a vanilla hashed-storage
from Hackage (ie. built against mmap-0.4). We do have users (mrothe and
presumably derrida) who exactly fit this description; and we have no
reason to believe that they are purposely jumping through any hoops to
build darcs against mmap-0.5.

So I think we have (a) assume there is some sort of Cabal bug and (b)
take concrete action (patch169) to cope with this [because it ultimately
does not matter where the bug lies if our users are tripping over it].

What's odd is that we're not getting more reports about this.  Either
users are being really really passive (or haven't upgraded yet), or
there are some sort pre-conditions that have to be fulfilled for this to
trigger, eg. you already have mmap-0.5 on your machine before you cabal
install darcs, or we're just missing something...
