+Subject: [PATCH] nspawn: ignore EEXIST when creating mount point
+
+A combination of commits f3c80515c and 79d80fc14 cause nspawn to
+silently fail with a commandline such as:
+
+  # systemd-nspawn -D /build/extra-x86_64 --bind=/usr
+
+strace shows the culprit:
+
+  [pid 27868] writev(2, [{"Failed to create mount point /build/extra-x86_64/usr: File exists", 82}, {"\n", 1}], 2) = 83

+
+The raw socket sd_event_source used for DHCP server solicitations
+was simply dropped on the floor when creating the new UDP socket
+after a lease has been acquired.  Clean it up properly so we're

+Subject: [PATCH] shared/install: avoid prematurely rejecting "missing" units
+
+f7101b7368df copied some logic to prevent enabling masked units, but
+also added a check which causes attempts to enable templated units to
+fail. Since we know the logic beyond this check will properly handle
+units which truly do not exist, we can rely on the unit file state
+comparison to suffice for expressing the intent of f7101b7368df.

+Subject: [PATCH] shutdown: fix arguments to /run/initramfs/shutdown
+
+Our initrd interface specifies that the verb is in argv[1].
+This is where systemd passes it to systemd-shutdown, but getopt
+permutes argv[]. This confuses dracut's shutdown script:
+  Shutdown called with argument '--log-level'. Rebooting!
+
+getopt can be convinced to not permute argv[] by having '-' as the first
+character of optstring. Let's use it. This requires changing the way
+non-option arguments (in our case, the verb) are processed.
+
+This fixes a bug where the system would reboot instead of powering off.
