The package at ( at-3.1.20-1.1.x86_64 ) has missing runtime dependency on
libfl2 on the latest Tumbleweed snapshot ( 20170825 )

When executing the at command on a fully patched up to date TW;
narf:~ # at
at: error while loading shared libraries: libfl.so.2: cannot open shared object
file: No such file or directory

narf:~ # rpm -q at
at-3.1.20-1.1.x86_64

After installing libfl2-2.6.4-2.1.x86_64 it functions as expected:

narf:~ # at
Garbled time

It seems at package needs Requires: libfl2 ?
