Hi, Jan!

No, sorry, you cannot do it.

First, we cannot add new RPM dependencies in GA (we tried once and had
to revert that change).

Second, there was already socat dependency in RPM, added by Nirbhay in

MDEV-6211 MariaDB-Galera-server uses 'socat', but 'socat' is not in the dependency list
commit bd5ca5e6093046d7e69cc59f0950a7af2c0a7bf2

removed by Nirbhay in

MDEV-7233: Fix issue with missing dependency socat when installing MariaDB-galera-server on RedhatEL/OracleEL/(Others?) RPM based
commit 41367e4023d0823624a461597813e6902437f096

I don't see a good solution for this issue. Adding socat to mariabackup
package aren't much better, as mariabackup users don't really need socat
either.

May be just a better error message in the script?
