I'll try this tomorrow.

It's no question, that I'd like to support those as well. But I do not expect ISP system administrators running a beta1 in production. I believe they want to testdrive a largely overhauled version in a testbed and see if it's bug-free. If it won't be that hard to produce different kernels, it'll be fine with me. kp ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ leaf-devel mailing list leaf-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-devel
