Implementation: getupdates funcs

• All changesets have to include funcs to get wrappers and install functions:

  • reads $WORKDIR / $LEADGOLD / $MACHTYPE (srv vs wks)
  • installlink: move a file out and make a symlink (like resolv.conf)
  • installfile: complex function that provides 8 ways to install a file
  • chattr: only run if argument is file, and skip symlinks
  • removefiles: delete file only if it's there, and after chattr -i
  • rotatefile: move a file out before a new one is installed (used by changesets and installfile, before replacing a stock file)
  • rpm/dpkg wrapper that removes expected stderr output
  • apt-get wrapper that defaults to -q –trivial-only for safety
  • apt-get-force when you really need it (apt-get -q -y)
