Hi,

as we now have sbuild in ISAR next, first users stumble upon issues when running the kas docker image in the gitlab-ci.
This requires additional mountpoints, as the schroot itself uses overlayfs and stacking two overlayfs is not possible.
By that, you have to mount the overlay from the host.

The kas-container script already has support for that, but it lacks documentation on how to configure this manually.
In short: The following mountpoint has to be added (as RW): /var/lib/schroot/union/overlay

As this is neither an ISAR issue, nor a KAS issue per-se, I send this to both lists.
