Subject: [OSSTEST PATCH v2 1/3] ts-depriv-audit-qemu: Create complete /run/user in appropriate root
Date: Tue, 20 Nov 2018 11:51:13 +0000	[thread overview]
Message-ID: <20181120115115.30556-1-ian.jackson@eu.citrix.com> (raw)

* Use mkdir -p, rather than trying to only create /run/user/$uid.
  That helps if /run and/or /run/user do not exist, as they do in
  libxl-made chroots with recent libxl (which gets qemu to chroot).

* Do all of this in the root directory of the qemu process, not our
  own root directory.  So it works if qemu is chrooted.

v2: Actually use $qpid rather than hardcoding 8123 !
