/*****************************************************************************
* DASD mount point setup *
* (c) 2000-2001 Bernhard Rosenkraenzer <bero@redhat.com> *
* v 0.2.1 - 2001/04/25 Helge Deller <hdeller@redhat.de> *
* - added commandline-parsing of the initial mountpoints *
* - exit program if user press the Cancel-button *
* - added check for existance of root-fs *
* v 0.2.0 - 2000/12/18 *
* initial release *
* TODO: sanity checks: *
* you can't mount different DASDs at the same mount point. *
