Use the directory specified by the shell environment variable TMPDIR for temporary objects creation and ngdump job simulation. If TMPDIR is not set, then use "/tmp" for the mentioned purposes; While running ngdump job in 'dry-run' mode: . Don't format/mount the target dump device. Instead, create the bootmap file and the meta-file at the temporary mount point without mounting anything to it. Thus, the mentioned files to be acrually created in the "proxy" file system owning the temporary mount point; . Retrieve base disk info from the read-only dump device and complete that info with the block size of the proxy file system; Separate the steps on retrieving/setting file system block size into a dedicated procedure; Use definitions instead of hardcoded file names; Fix a bug in an error path (accessing freed memory); Make misc_open_simulate() and misc_open_exclusive() static; Update man pages with the requirements on the system environment (resources) for ngdump job being executed in dry-run mode; Provide hints for user (in stderr) in case when ngdump job in dry-run mode failed due to inappropriate system environment.
