Hi Dan, where/how did you hit this issue exactly? Is this about the autopkgtest.ubuntu.com or running autopkgtest locally? In the latter case, which version, and which virt-server are you using?
Newer versions of autopkgtest should not use a tmpfs for /tmp: autopkgtest (5.36) unstable; urgency=medium [...] * setup-testbed: prevent /tmp from getting a tmpfs mount (LP: #2069834) so we need more info to triage this bug. Thanks! ** Changed in: autopkgtest (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Canonical's Ubuntu QA, which is subscribed to autopkgtest in Ubuntu. https://bugs.launchpad.net/bugs/2078981 Title: nodev tmp - should autopkgtest ensure that AUTOPKGTEST_TMP is available for dev node creation? Status in autopkgtest package in Ubuntu: Incomplete Bug description: 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.
