Package: backup2l
Version: 1.6-2
Severity: minor
Dear maintainer,
after upgrading tar to 1.30+dfsg-2 it complains about positional
parameters being incorrectly set when used by backup2l:
Creating archive using 'DRIVER_TAR_GZ'...
tar: The following options were used after any non-optional arguments
in archive create or update mode. These options are positional and
affect only arguments that follow them. Please, rearrange them
properly.
tar: --no-recursion has no effect
tar: Exiting with failure status due to previous errors
The archives seem to be created correctly, so there should be no
regression in functionality.
tar is being invoked as
tar czf $3 -T $4 --no-recursion 2>&1
To fix the warning, the --no-recursion parameter should be placed in
front of -T
tar czf $3 --no-recursion -T $4 2>&1
This affects the drivers DRIVER_TAR, DRIVER_TAR_GZ and DRIVER_TAR_BZ2,
including some other options.
Cheers,
Markus
