It seems this discussion has gone stale, but this is still broken on some systems. This is gcc135 on the GCC Farm, which passes the prereq this commit adds: $ systemd-analyze verify systemd/user/git-maintenance@.service Failed to open /dev/tty0: Permission denied Failed to load systemd/user/git-maintenance@.service: Invalid argument I don't know the systemd specifics involved, but this seems like a rather straightforward problem of assuming permissions that aren't universal. I.e. let's try to do that in the prereq instead? OS details, if they matter: [avar@gcc135 t]$ systemd-analyze --version systemd 219 +PAM +AUDIT +SELINUX +IMA -APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 -SECCOMP +BLKID +ELFUTILS +KMOD +IDN [avar@gcc135 t]$ cat /etc/centos-release CentOS Linux release 7.9.2009 (AltArch)
