           Summary: rsync fills the disk blocking the system
           Product: rsync
           Version: 3.1.0
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: P3
         Component: core
        AssignedTo: wayned at
        ReportedBy: giampaolo.ferradini at
         QAContact: rsync-qa at

in a situation where rsync was instructed to sync a home directory tree with a
second hard drive normally mounted in /media, the command executed even if no
such drive was mounted and filled the main drive completely, preventing the
system from booting.

i would like to draw a few issues to attention:
- rsync should have a check that prevents it from making the disk unusable,
i.e. from filling it to the point of disrupting the boot process;
- i would recommend a "check space required" and confirmation request in case
space is not sufficient to complete the task;
- in case a /media folder is involved, i would suggest a confirmation request
in case there is no volume currently mounted, to prevent rsync from creating
undesired directories.

kindest regards
