Subject Re: GroupId for DayTrader needed.
Date Thu, 20 Jul 2006 23:01:52 GMT
It is not just how we use the m2-style repo inside of G, but also how  
we build G using m2 that will cause problems for windows peeps.

The later is going to be more trouble to resolve I think.

I'm still thinking it would be a good idea to have some sort of file- 
system abstraction for our m2-style repo... in the same way that SVN  
has an abstraction... that could use BDB or a regular file system  
(ie. FSFS) for actual storage.  WIth something like this, we could  
have the default distro use a BDB-ish filesystem and completely  
resolve the windows file name limitations.  With a set of cli tools  
we can easily allow the BDB-ish to be converted to a FSFS.

Short of hacking up G to work around the problem... I don't see any  
other clean way to resolve this problem for our windows users.
