[Koha-devel] Thoughts on retiring libapache2-mpm-itk?

[Fridolin SOMERS]

Hi David,

We simply have one Koha per system, using LXD containers.

nginx and starman are in this container and are run by www-data user.
Since cronjobs are run by a "koha" user we had some file permissions 
issues that we patched in our fork.

For a few customers we have Apache, running with MPM Event.

Best regards,
