Why Scientific Linux?
For those who are familiar with my install guides, I have been producing Fedora install guides for many years. With recent Linux distributions, there has been a number of issues with the Access Grid software (particular ally since Fedora 14), with some testing pointing to versions of python-twisted causing some of the problems
