Subject: [PATCH] cc_mounts: fix incorrect format specifiers (#316)
RH-Author: Eduardo Otubo <otubo@redhat.com>
Message-id: <20200825131749.4989-1-otubo@redhat.com>
Patchwork-id: 98217
O-Subject: [RHEL-8.3.0 cloud-init PATCH] cc_mounts: fix incorrect format specifiers (#316)
Bugzilla: 1794664
RH-Acked-by: Mohammed Gamal <mgamal@redhat.com>
RH-Acked-by: Cathy Avery <cavery@redhat.com>
Conflicts: Not exactly a conflict, but removed optional notations
"variable: type" and "-> type" from function header create_swapfile() as
it is only available on Python >= 3.5 and this patch is for RHEL-7.9
only (Python 2.*). The rest of the cherry-pick was clean.
