  • Adds a mr-device-mounted binary to MondoRescue? (replaces the code of the C function is_this_device_mounted) and the corresponding perl function (mr_device_mounted) to handle cases where a mounted device has a different name than the one seen on mount (e.g. /dev/rhel/root and /dev/mapper/rhel-root)
  • Adds perl function mr_file_copy_and_erase_hash to empty the hash generated in mr_file_read_all_link and thus avoid filling the hash it generates, which is useful for a recursive function, but not when called multiple times from another perl script. To be improved later on.
  • Adapt build procedure to the new binary (tested on Mageia 5 and RHEL7)

     89This function erases all elements in the hash passed in parameter (such as the one created in mr_file_read_all_link)
     90Takes as param the hash to delete and returns a new fresh one

    89110This function returns all the links found for a given file passed as parameter
    90111Example: mr_file_read_all_link(/lib64) returns (/lib64,/usr/lib64) on a system having a link from /lib64 to /usr/lib64
    91 The return value is a hash of all input files pointing to hash of links
     112The return value is a hash of all input files pointing to the hash of their links
     113That hash needs to be cleaned up after usage
