Space Considerations

The Smart Installation System requires a place to ``stage'' the installation. By default this is the current working directory when you invoke RTR. However, you may set the environment variable TMPDIR to tell the installation system to ``stage'' each package in the TMPDIR directory instead.

The amount of space required by each package is displayed by the installation system just before the system asks you if you want to install the package.

During installation, the amount of space used is never more than the sum of:

1. The installation system (less than one megabyte) (``stage'' area)
2. The package being installed (the entire package gets ``unpacked'', even if you don't install all of it) (``stage'' area)
3. The largest file in the package (``install'' area)

Files that you choose not to install (e.g. formatted man pages) are removed from the ``stage'' area before the space is allocated for step 3.
