Description Alexandru Palalau 2013-07-17 15:33:07 UTC
BUILD: 1.5_M3: 3dee534f1e25109e0bdb681de0746c336f4b8840
ENVIRONMENT: Fedora 17
STEPS TO REPRODUCE:
1. Prepare a core-image-sato image with systemd support and launch it. 
     Refer to TC-549 in order how to build it.
2. List all the failed services by running the following command:
    $ systemctl --failed
   No failed services at this point
3. Check df output

tmpfs                    58584        92     58492   0% /var/volatile

4. List all the failed services by running the following command:
    $ systemctl --failed

UNIT                          LOAD   ACTIVE SUB    DESCRIPTION
proc-sys-fs-binfmt_misc.mount loaded failed failed Arbitrary Executable File Formats File System

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
Comment 1 Ross Burton 2013-07-23 15:27:58 UTC
systemctl should be able to give you the log from starting that service that failed.  Maybe that kernel doesn't have binfmt_misc support?

Assigning to Radu for the next step of debugging.
Comment 2 Ross Burton 2013-09-04 16:22:52 UTC
Some of the qemu machines were not recommending kernel-modules, so they didn't have the binfmt-misc modules installed.  Patch sent.
Comment 3 Ross Burton 2013-09-06 14:47:07 UTC
That patch rejected.  Second patch almost send and then self-rejected.  Patch three sent!
Comment 4 Ross Burton 2013-09-10 10:36:36 UTC
Merged as oe-core d42f7fc333495dc35227a6d1027492ab70f29b23
