Public bug reported:

Related bugs: LP: #2075546, LP: #2078980

It appears that an implication of systemd tmp.mount is that /tmp may be
mounted as nodev, as can be seen in some cases now when using the qemu
backend for an Oracular image.

autopkgtests running in an isolation-machine environment would
reasonably conclude that they could create device nodes, certainly a
requirement for livecd-rootfs and I expect others.

AUTOPKGTEST_TMP today is of the form
/tmp/autopkgtest.tA1oiD/autopkgtest_tmp in the current setup, so /tmp
being nodev should mean that AUTOPKGTEST_TMP is as well.

As an explicit interface, I suggest that AUTOPKGTEST_TMP should be
located somewhere that dev nodes can be created.
