Package: systemd
Version: 215-17+deb8u6
Severity: normal

Hi, on jessie (amd64 kvm/qemu VM) I can reliably trigger this:

| systemd[1]: Got automount request for (null), triggered by 1767 (ls)
| systemd[1]: Assertion 'path' failed at ../src/shared/mkdir.c:79, function mkdir_parents_internal(). Aborting.
| systemd[1]: Caught <ABRT>, dumped core as pid 1768.
| systemd[1]: Freezing execution.

assertion error as follows:
} (Ensure proc-sys-fs-binfmt_misc.automount is not masked)
} 
} ### disable module loading
} echo 1 > /proc/sys/kernel/modules_disabled
} 
} ### trigger binfmt automount
} ls -l /proc/sys/fs/binfmt_misc/
} 
} ### check that proc-sys-fs-binfmt_misc.mount has failed
} systemctl --failed
} 
} ### mask the automounter
} systemctl mask proc-sys-fs-binfmt_misc.automount
} 
} ### tail the jornal (optional)
} journalctl -f &
} 
} ### trigger the assertion error
} ls -l /proc/sys/fs/binfmt_misc/

This came up because we mask proc-sys-fs-binfmt_misc.automount using
puppet and then systemd froze on all our hosts and things were very sad
until the world got rebooted.

Cheers,
