Hi, Reindl!

i am missing something (probably simple like symbol versioning however

I'm not quite sure.
I used to think that symlinks don't solve the issue,
and one needs the correct SONAME value inside the dynamic library.
And I created MDEV-9294.
But many people were asking for and complaining about symlinks, and
nobody said that they didn't help. So I thought that may be I
misunderstood the documentation and symlinks are enough.
Now it looks like we might still need to imlement MDEV-9294 after all...
looks so
the other option for downstream is take 10.1.x sources and build a
"mariadb-libs-compat" only install the client libraries which was done
in 3rd party repos years ago to somehow get a newer mysql version
without breaking already installed apllications and to avoid collisions
between 3rd party and distribution packages
IMHO such things should be considered through development and rename
things because with my admin hat on i would never ever do a dist-upgrade
with introduces a major upgrade of critical packages like mariadb/mysql,
php, dovecot, postfix and the last 10 years i spent much energy to
always get this upgrades out with the old distro version
upgrade/downgrade a single piece of the software is much nicer than sit
after the dist-upgrade with "this should not have happened and was not
isible in all the tests"
smooth transitions between major versions are the key for fast adoption
and there are not much sysadmins like me which are also capable to build
packages, write most of the software inhouse and control/build/prepare
neartly any piece of software in the whole infrastructure - frankly, i
donät know how i would all this things wihtout beeing able to to all
that jobs at once - stick on a CentOS with ages old software for decades
is also not a solution
attached my current rpm-spec - the server itself works fine and i
really want to avoid building a "server-only" package for the whole
lifetime of Fedora25/26 as well as not wait for Fedora 27 to get
10.2.x
