logs/x86_64.log is the pungi log. I forgot to look at work/x86_64/log/pylorax.log but perhaps the console message could remind me. Looking through the output from "strace -f -s 256 pungi ..." I see that the text "undefined symbol: set_com_err_gettext" appears only once, where it is first generated. So if that message was written to a log somewhere, then it is not in the first 256 characters of the write*(). lorax-17.10-1.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/lorax-17.10-1.fc17 lorax-17.12-1.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/lorax-17.12-1.fc17 lorax-17.12-1.fc17 has been pushed to the Fedora 17 stable repository. If problems still persist, please make note of it in this bug report. |
Description of problem: stderr of the subprocess for mkfs root.img is not logged, so the log omits necessary information when the mkfs fails. Version-Release number of selected component (if applicable): lorax-17.1-1.fc17.x86_64 How reproducible: every time Steps to Reproduce: 1. Setup mkfs.ext4 to fail during resolution of shared libraries. For instance, install libcom_err.x86_64 0:1.41.14-2.fc15 instead of libcom_err.x86_64 0:1.42-1.fc17 so that the symbol set_com_err_gettext will be missing for e2fsprogs-1.42-1.fc17.x86_64 2. Invoke pungi-2.9-1.fc16.noarch to create an install DVD for rawhide for Fedora 17, for instance via setenforce 0 /usr/bin/pungi -c fedora-install-fedora-17.ks \ --destdir=$DESTDIR --name Fedora --ver $VERSION --nosource 3. Actual results: lorax log file logs/x86_64.log ends with: ----- pylorax.ltmpl.DEBUG: template line 846: runcmd chroot /ext4/Fedora17/work/x86_64/yumroot find -L /etc /usr /lib -xdev -type l -delete pylorax.INFO: creating the runtime image ----- Note in particular there is no message regarding failure of mkfs.

Expected results: The error message about "undefined symbol: set_com_err_gettext" should appear in the lorax log so that the user gets a good clue about what is wrong and how to fix it.
