source: branches/stable/mondo/src/mondoarchive/main.c @ 1087

Last change on this file since 1087 was 1087, checked in by bruno, 12 years ago

WARNING: Not tested yet ! Will be stabilized in next hours.
this patch changes the interface between mindi and mondo.
Everything is now managed through either MONDO_CACHE/mondo-restore.cfg
and MONDO_CACHE/mindi.conf (an additional configuration file)
This removes all the one line files NFS-*, ... that where used
in an anarchic way. Now everything computed by mondo is
under mondo-restore.cfg and everything related to mindi in mindi.conf

Still needed are the removal of the 2 parameters to mindi,
but that will be done after when a clear line is drawn between
where files are put by each tool.

MONDO_TMP and MINDI_TMP should be reserved for temporary files
MONDO_CACHE and MINDI_CACHE for end results and communication
between tools.
These changes were made in order to prepare the USB support in mondo

A first step in the right direction, but still some work to do
before it's working again.
Testers please be warned.
