Hi Tom,

This is my current thinking with regard to a LXC Container system for building OS images and support software.
The host workstation has all the standard development tools ('build-essential' etc) that any/all containers would normally need.
This can be updated as required (in effect, updating all containers).

The containers must run unprivileged as the both the software being built and the build software itself may be of dubious quality (especially if I wrote it).

      bind,ro mounts the host filesystem providing development tool access
      overlayfs a delta filesystem on which required tools\libraries etc can be built

ContainerN: repeat above as often as required

bind,ro mounts the host filesystem providing development tool access
bind,ro mounts CN deltas to provide access to the tools\libraries
overlayfs a delta filesystem on which the test OS can be built

Can you:
see anything wrong with the proposed above where container superuser privileges and device access would allow corruption of either the Host or of a neighbouring container ?
think of anything builds require that I have not made allowance for ?
detail a better way for obtaining my goal ?

Appreciate your comments Tom.
