i am missing something (probably simple like symbol versioning however done with some hack) or is it really not possible by providing symlinks to avoid "libmysqlclient.so.18 => not found" and all clients linked against 10.1.x failing? 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 [root@testserver:/usr/lib64/mysql]$ ls insgesamt 308K lrwxrwxrwx 1 root root 13 2017-07-13 13:15 libmysqlclient.so.18.0.0 -> libmariadb.so lrwxrwxrwx 1 root root 13 2017-07-13 13:15 libmysqlclient.so.18 -> libmariadb.so -rwxr-xr-x 1 root root 305K 2017-07-13 13:15 libmariadb.so.3 lrwxrwxrwx 1 root root 15 2017-07-13 13:15 libmariadb.so -> libmariadb.so.3 lrwxrwxrwx 1 root root 17 2017-07-13 13:15 libmysqlclient_r.so -> libmysqlclient.so lrwxrwxrwx 1 root root 13 2017-07-13 13:15 libmysqlclient.so -> libmariadb.so [root@testserver:/usr/lib64/mysql]$ ldd /usr/sbin/dbmail-imapd linux-vdso.so.1 (0x00007fff2fdfd000) libgmime-2.6.so.0 => /lib64/libgmime-2.6.so.0 (0x00007f0b0fd94000) libgobject-2.0.so.0 => /lib64/libgobject-2.0.so.0 (0x00007f0b0fb42000) libglib-2.0.so.0 => /lib64/libglib-2.0.so.0 (0x00007f0b0f82f000) libevent-2.0.so.5 => /lib64/libevent-2.0.so.5 (0x00007f0b0f7e5000) libzdb.so.11 => /lib64/libzdb.so.11 (0x00007f0b0f7d0000) libdbmail.so.0 => /usr/lib64/dbmail/libdbmail.so.0 (0x00007f0b0f759000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f0b0f53b000) libc.so.6 => /lib64/libc.so.6 (0x00007f0b0f175000) libgio-2.0.so.0 => /lib64/libgio-2.0.so.0 (0x00007f0b0ede2000) libz.so.1 => /lib64/libz.so.1 (0x00007f0b0ebcc000) libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f0b0e95a000) libffi.so.6 => /lib64/libffi.so.6 (0x00007f0b0e750000) libmysqlclient.so.18 => not found libm.so.6 => /lib64/libm.so.6 (0x00007f0b0e447000) libdl.so.2 => /lib64/libdl.so.2 (0x00007f0b0e243000) libssl.so.10 => /lib64/libssl.so.10 (0x00007f0b0dfd1000) libcrypto.so.10 => /lib64/libcrypto.so.10 (0x00007f0b0db70000) libgmodule-2.0.so.0 => /lib64/libgmodule-2.0.so.0 (0x00007f0b0d96a000) libgthread-2.0.so.0 => /lib64/libgthread-2.0.so.0 (0x00007f0b0d768000) libmhash.so.2 => /lib64/libmhash.so.2 (0x00007f0b0d53c000) libevent_pthreads-2.0.so.5 => /lib64/libevent_pthreads-2.0.so.5 (0x00007f0b0d538000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007f0b0d302000) /lib64/ld-linux-x86-64.so.2 (0x0000559e18ffe000) libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f0b0d0db000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00007f0b0cebe000) libmount.so.1 => /lib64/libmount.so.1 (0x00007f0b0cc74000) libgomp.so.1 => /lib64/libgomp.so.1 (0x00007f0b0ca46000) libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x00007f0b0c7f9000) libkrb5.so.3 => /lib64/libkrb5.so.3 (0x00007f0b0c513000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00007f0b0c30f000) libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x00007f0b0c0dc000) libfreebl3.so => /lib64/libfreebl3.so (0x00007f0b0bed9000) libblkid.so.1 => /lib64/libblkid.so.1 (0x00007f0b0bc96000) libuuid.so.1 => /lib64/libuuid.so.1 (0x00007f0b0ba91000) librt.so.1 => /lib64/librt.so.1 (0x00007f0b0b889000) libkrb5support.so.0 => /lib64/libkrb5support.so.0 (0x00007f0b0b678000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00007f0b0b474000)
