Changeset 2424 in MondoRescue for branches/2.2.9/mondo/src


Ignore:
Timestamp:

Author:
Bruno Cornec
Message:
  • analyze-my-lvm now removes excluded devices from list coming from mondoarchive
  • new mr_make_devlist_from_pathlist which handle the new bkpinfo->exclude_devs field containing the excluded devices and remove corresponding code from libmondo-cli.c
  • Move DSF code into libmondo-devices.c for coherency, and only the previous function is made externally available
  • Remove dev_to_exclude in libmondo-archive.c which wasn't working correctly and replace it with bkpinfo->exclude_devs
