On a fresh Ubuntu 16.04 I tried to install mysql-server with an extra ext4
volume mounted at /var/lib/mysql, but the installation failed:

Apr 21 06:46:27 cloudcentric-base-image-ubuntu-16 mysql-systemd-start[13362]:
MySQL system database not found in /var/lib/mysql. Please run mysqld

Executing the suggested command shows this

directory has files in it. Aborting.
2017-04-21T06:53:53.587746Z 0 [ERROR] Aborting
At this time the only files in /var/lib/mysql are:
# ll /var/lib/mysql

drwxr-xr-x 46 root root 4096 Apr 21 06:46 ../
-rw-r--r-- 1 root root 0 Apr 21 06:46 debian-5.7.flag
drwx------ 2 mysql mysql 16384 Apr 21 06:44 lost+found/
Removing debian-5.7.flag doesn't change anything.
Removing everything from the directory works. mysqld --initialize finishes
without error. Removing the mysql packages and executing apt install
mysql-server again on an empty /var/lib/mysql works fine.
Searching the web, their are already bug reports present, like:
https://bugs.mysql.com/bug.php?id=22615
These suggest to fix this issue with --ignore-db-dir=lost+found
