Get Appliance Info

Introduction

All OpenVZ appliance templates created with Debian Appliance Builder will have the dab.conf file embedded in them as ./etc/appliance.info - the leading ./ is important as that is the way it has been archived.

A concatenation of all such appliance.info files separated by atleast 1 newline each along with Location and md5sum lines and removal of the Architecture, Installed-Size and Source lines is what essentially makes up the content of the /var/lib/pve-manager/apl-info/apl-available file (in PVE v1.x, the apl-info folder is not present and hence removed from the path listed here).
