YAIM's directory structure

The standard location of the installation is /opt/glite/yaim. Here several ddirectories are located, e.g.:

  • /functions/: Contains the functions the configure each node types.
  • /functions/local/: If you need to change a function you leave the origional file in place and have your copy with changes in the directory functions/local (same file name). This files are then used instead of the origianal functions.
  • /node-info.d/: Every resource installed creates a file with a list of for the configuration required functions.
  • /examples/: Here example files of the users and groups configuration can be found. They contain settings for all LHC VOs, dteam and ops.
  • /examples/siteinfo: In this directory an example for the central site configuration file is stored - the site-info.def.
