[pmg-devel] [PATCH proxmox-mailgateway 4/4] add initial-freshclam.service to pmg-container

[Stoiko Ivanov]

the proxmox-mailgateway-container metapackage is used to build our
Mailgateway container template with 'dab'. When creating the template
clamav-freshclam gets installed, but does not download the virus-definitions
resulting in 'clamav-daemon' not starting upon first boot of the PMG
container.

By adding a service file which invokes 'freshclam' and blocks until the files
are downloaded, which adds a dependency on itself to clamav-daemon the daemon
starts successfully on the first boot of a container.

Not needed for non-container installations.

Tested by adding and enabling the service file on a freshly created (and never
started) pmg-6.1 container and booting it - clamav was running happily after
the download. After a reboot the service did not run because
of the ConditionPathExistsGlob
