We are using MySQL / MariaDB for many years but current pkg upgrade of Mari=
aDB
10.3 ends up with broken configuration where daemon was unable to start with
strange error message in the log:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.3.25-MariaDB
key_buffer_size=3D134217728
read_buffer_size=3D131072
max_used_connections=3D0
max_threads=3D153
thread_count=3D0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads =3D 467=
360 K=20
bytes of memory
Hope that''s ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom =3D 0x0 thread_stack 0x49000
0xcd7b7c <my_print_stacktrace+0x3c> at /usr/local/libexec/mysqld

The manual page at
https://mariadb.com/kb/en/how-to-produce-a-full-stack-trace-for-mysqld/
contains
information that should help you find out what is causing the crash.


This was tracked down to /usr/local/etc/my.cnf which was replaced by some
"empty" configuration file:

> cat /usr/local/etc/my.cnf
#
# This group is read both by the client and the server
# use it for options that affect everything
#
[client-server]

#
# include *.cnf from the config directory
#
!includedir /usr/local/etc/mysql/conf.d

Original my.cnf was not moved in to /usr/local/etc/mysql/conf.d nor backed =
up.=20
To make this instance work again I must restored my.cnf from backup.

This very same problem was seen on another machine with upgrade from 10.3.2=
3 to
10.3.27. This first machine was upgraded from 10.3.23 to 10.3.25.

I think this behavior is very dangerous a should be avoided - no user modif=
ied
configuration files should be replaced by pkg install / pkg upgrade.

If this is really REALLY necessary then it should be mentioned in UPDATING
and/or pkg-message but this is not the case here.

>From user / administrator perspective I really do not expected to "pkg upgr=
ade"
breaks configuration forking for years.
