[Bug 1847848] [NEW] eoan-desktop-amd64 20191011 zfs install out of memory

[Tom Reynolds]

Public bug reported:

Doing a default installation with the ZFS option enabled, on a system
with 2.0 GB physical RAM (actually a Virtualbox VM), the installation
went out of memory and OOM killer kicked in, stopping the desktop and
leaving me with a shell which just printed OOM messages for additional
processes. The system did not recover from this after 5 minutes.

One of the processes OOM killer killed was 'unattended-upgrade' - maybe
this does not need to be running on a live image during installation?
