Right, this is a mistake in that file, but we actually don't need to get pid-file from /etc/my.cnf at all, since we have the daemon pid as the first argument from systemd unit file.

The value pid-file is read by mysqld_safe and passed to mysqld in practice. So this doesn't have to be changed, imho.

all mistake would be nice to patch sooner or later:-)

at the same time another (imho required) patch would be to patch all /usr/share/mysql/my-*.cnf file and the original /etc/my.cnf too to append this to the end:
-------------------------------
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
-------------------------------
otherwise mysqld_safe pass a wrong argument. this is mentioned in your mariadb-logrotate.patch

anyway this whole mysql - mysqld - mariadb naming mass should have to cleared (probably also the upstream too), but /var/lib/mysql dir and mysql database sharedir, includedir etc... i see the reason of being compatible with mysql but it doesn't seems to be too clear way.

I'd rather add a recommendation of how these files should be correctly used, since it is better not to replace the original my.cnf file, but rather extend it with the configuration from /usr/share/mysql/my-*.cnf files. So, I'd rather add a README file containing:
"""
This directory contains prepared configuration files with .cnf extension,
which provide a configuration for some common MariaDB deployment scenarios.
These configuration files do not include the default configuration of datadir,
log-file and pid-file locations, as specified in the default my.cnf file,
provided in this distribution.

Thus, it is recommended to use these configuration files as an addition to the
default my.cnf configuration file.

Since default my.cnf contains `!includedir /etc/my.cnf.d` directive, it is
recommended to copy required configuration under /etc/my.cnf.d/ directory,
so the default my.cnf specifications will be extended.
"""

The original issue mentioned in comment #0 can lead to an issue, that the server won't be able to start. It can be reproduced by:
1) remove pid-file specification in /etc/my.cnf
2) systemctl start mariadb

Current behaviour:
Server is not started.

Expected behaviour:
Server is started and pid file is in /var/lib/mysql/`hostname`.pid.

Well, true. The reason for that was that the cnf files have been installed into two locations as well since ages (/usr/share/mysql and /usr/share/doc/mysql-server). So, maybe it would be better to install the .cnf files and README only to /usr/share/mysql as upstream does it.

spec file for el6

this is my latest'n'greatest spec for mariadb on rhel6. although it's not for el7 but imho it contains a lot's of bugfix relative to the current one in rhel7 beta.
as rhel7 should have to be able to updated from rhel6 (this's one of the biggest new feature of rhel7 as announced) the maraidb should have to have to be able update rhel6's mysql. of course the systemd <-> upstart differences not relevant to the el7 spec file.

so a few comment:
 * this above is the reason for /var/lib/rpm-state files
 * libmysql version updated to the fedora's one
   * droped libmysql.version, mariadb-versioning.patch, mariadb-dubious-exports.patch
   * added mariadb-versioning-compat.patch
 * a few more new patches
 * pam-devel for auth_pam.so plugin
 * add relevant oboslates
 * add relevant provides
 * mysql_cofig moved from base to devel (as in fedora) and also alternative too
 * path update to 5.5.35
 * run mysql_upgrade since it's required to be able to update from mysql
 * always stop mysql in pre since after mariadb file are installed you're not able to stop or even restart the old mysql serivce
 * add proper chkconfig
 * if mysql was run before update start in posttrans
 * add proper altrenative to the proper scripts section

i hope it will help.

Thanks Levente for the proposal, we appreciate that and we're taking that into consideration. However, we won't be able to cover all the issues, like running mysql_upgrade automatically -- we find it too dangerous to do something like that automatically; the configurations can be too different from our expected state. However, users will be instructed to do so on their own.

in the latest version i also comment it out since if root has password on localhost it's not working.
but most imho the latest spec still has a few fixes to the original ones.
