Beyond these packages, yes, it has to be in their stack (or there can be a request to LCG to package anything that a significant number of VOs want - and that probably is a GDB decision). > > I don't want to have to read the "WN requirements doc" for fourteen > separate VOs ... Indeed. With a metarpm system we don't have to - and we can use the tools we have (apt, yum, rpm) to intelligently get the necessary union of VO required rpms. We've seen really daft things happening - sites enabling phenogrid, but jobs failing because of lack of an f77 compiler. > > Henry Nebrensky wrote: > >> >> Should Atlas be allowed to modify "LCG" RPMs? No. But neither does it make sense for every site to have to parse Atlas's list.

Cripes! So then you let the VO trigger an install of any rpm at your site. Please no.... cheers g -- -------------------------------------------------------------------- Dr Graeme Stewart http://www.physics.gla.ac.uk/~graeme/ GridPP DM Wiki http://wiki.gridpp.ac.uk/wiki/Data_Management
