Q&A

  • Alex: Is there an overview of changes planned for EasyBuild v5.0?
  • Alex: Should we consider moving all bundles to use components rather than extensions?
    • currently we can only install bundles of components from scratch (while installed extensions can be skipped)
    • there's also integration of extensions into Lmod (so they can be searched via "module spider")
    • extensions have non-obvious limitations (like modextravars not being picked up)
    • best way to support this would be to implement "native" support for a bundle of components in EasyBuild framework?
  • Kurt: should implement support for short_description to determine what goes into whatis line in module name
  • Jörg: problem with software that is downloading stuff in particular folders
