Hi, Today I am experiencing build failures of several packages when using the devtools: $ extra-x86_64-build -- -I ../../another-package/trunk/foo.pkg.tar.xz (...) ==> Making package: ring-gnome 3:20180112.2.d0bda53-1 (Sun Jan 14 16:06:22 CET 2018) ==> Retrieving sources... -> Updating ring-client-gnome git repo... Fetching origin ==> Validating source files with sha256sums... ring-client-gnome ... Skipped Failed to attach 9683 to compat systemd cgroup /user.slice/user-1000.slice/session-c1.scope/payload: No such file or directory Failed to attach 9661 to compat systemd cgroup /user.slice/user-1000.slice/session-c1.scope/supervisor: No such file or directory Failed to chown() cgroup /sys/fs/cgroup/systemd/user.slice/user-1000.slice/session-c1.scope/payload: No such file or directory Parent died too early ==> ERROR: Build failed, check /var/lib/archbuild/extra-x86_64/zorun/build Full log : https://paste.aliens-lyon.fr/gD0 This is the ring-gnome package in [community] but I had this issue with another one. It's not 100% reproducible, but when it happens, all subsequent builds of the same package exhibit the issue. My system is fully up-to-date, with kernel 4.14.13-1-ARCH and systemd 236.0-3. It looks like a bug in systemd, or in the interaction with the devtools. This may be caused by the systemd update a few days ago. Any idea? Baptiste
