(In reply to comment #0) > (And the complaint looks bogus anyway because it does not give > the name of the file which supposedly has "Exec format error".) Yes, it is bogus. There is no such executable. "Exec format error" in this case does not come from any execve() call. systemd produces this error code internally. In transaction_verify_order_one(): ... log_error("Unable to break cycle"); ... return -ENOEXEC; Either a more appropriate error code should be used here (but which one?) or transaction_activate() should simply stop printing the string representation of the error code when reporting "Requested transaction contains an unfixable cyclic ordering dependency". The cycles with udev-retry.service should be gone with the current systemd and udev. (In reply to comment #1) > Either a more appropriate error code should be used here (but which one?) EDEADLK? ECANCELED? EINVAL Invalid argument which is true: there should be no cycles. Also EINVAL has a reputation as the "catch-all" error for "bad input" if nothing more specific can be identified. This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora19 We don't show the internal error anymore (at least since v44): Dec 03 15:08:43 fedora20 sudo[14205]: test : COMMAND=/bin/systemctl start cyclic2 Dec 03 15:08:43 fedora20 systemd[1]: Found ordering cycle on cyclic2.service/start Dec 03 15:08:43 fedora20 systemd[1]: Found dependency on cyclic2a.service/start Dec 03 15:08:43 fedora20 systemd[1]: Found dependency on cyclic2.service/start Dec 03 15:08:43 fedora20 systemd[1]: Unable to break cycle Dec 03 15:08:43 fedora20 systemd[1]: Requested transaction contains an unfixable cyclic ordering dependency: Transaction order is cyclic. See system logs for details. And on the console: Failed to start cyclic2: Transaction order is cyclic. See system logs for details. Looks OK to me. |
Created attachment 489907 [details] /var/log/messages Description of problem: Booting beta TC1 of Fe[d]ora-15-Beta-x86_64-Live-Desktop.iso from USB flash memory gives more than a dozen repetitions of a many-line complaint, each containing several repetitions of: systemd-ask-password-plymouth.path/stop would change existing job. Deleting systemd-ask-password-plymouth.path/stop to minimize impact. Once is enough. (And the complaint looks bogus anyway because it does not give the name of the file which supposedly has "Exec format error".) Version-Release number of selected component (if applicable): systemd-20-1.fc15.x86_64 How reproducible: every time Steps to Reproduce: 1. Boot beta TC1 of Fedora-15-Beta-x86_64-Live-Desktop.iso. Remove "quiet rhgb" from the kernel command line, in order to become aware of the messages. 2. Look in /var/log/messages after boot. 3. Actual results: More than a dozen repetitions of the same complaint, each complaint containing about 7 repetitions of: systemd-ask-password-plymouth.path/stop would change existing job. Deleting systemd-ask-password-plymouth.path/stop to minimize impact. and ending with: Requested transaction contains an unfixable cyclic ordering dependency: Exec format error Expected results: Only one complaint per error. No "Exec format error" in the first place. If really so, then give the name of the file which had the Exec format error. Additional info:
