source: MondoRescue/branches/2.2.10/mondo/src/common/libmondo-cli.c@ 2428

Last change on this file since 2428 was 2428, checked in by Bruno Cornec, 15 years ago
  • Attempt to stay backward compatible without protocol for -n option
  • Improving ssh support at restore time by providing a shadow file
  • 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
  • Fix an issue in is_this_device_mounted (string freed before last usage)
  • Adds support for bnx2x (BL 460 G6) and auth_rpcgss (Debian 2.6.31)

(Backport from 2.2.9)
  • Property svn:keywords set to Id
