Re: [Tarantool-patches] [PATCH 0/2] tarantoolctl --show-system

[Alexander Turenko <alexander.turenko@tarantool.org>]

This patchset formally fixes the issue, however I prefer to use the
following syntax:

$ tarantoolctl cat --show-system 00000000000000000000.snap

rather then one of the following

$ tarantoolctl cat --show-system true 00000000000000000000.snap
$ tarantoolctl cat --show-system 1 00000000000000000000.snap
$ tarantoolctl cat --show-system=true 00000000000000000000.snap
$ tarantoolctl cat --show-system=1 00000000000000000000.snap

I reopened the issue and will prepare the patch soon.

WBR, Alexander Turenko.
