(In reply to Jan Pokorný from comment #0) > Not sure if anything changed for el7, but if not, "image changes" [*] are > hopefully still possible. Please at least verify whether or not something has changed since rhel06 before opening a bug about it. I reported the original problem, thanks for opening this again. =) According to Harold Hoyer the issue still exists for Dracut generated ramdisk images (E.G. Anaconda boot images) on Fedora 19. Samantha, I'm sorry for the rush but it's like RHEL7 now or never, it seems. In fact the script as in [bug 1009596] worked well in el7 snapshot. Strange. Will provide more info.

Will provide more info. Can you please give a generic example of the process substitution in bash? If your process substitution uses <(list) then it would fail unless the symbolic link exists from /dev/fd/ to /proc/self/fd Follow the steps to reproduce in Bug #814850 Jon, the respective part of %post, used both for el6.5 (as in [bug 1009596]) and el7 snapshots, looked like this in my case: > %post > rpm -Uvh "http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm" > mv /etc/yum.repos.d/epel.repo{,.orig} > # this is quick'n'dirty way to add excludes (no checks + debug package handling) > echo "exclude=python-repoze-who-friendlyform" | cat <(head -n+2 /etc/yum.repos.d/epel.repo.orig) - <(tail -n+3 /etc/yum.repos.d/epel.repo.orig) >/etc/yum.repos.d/epel.repo > %end (it was arranged like that as the ks file itself was generated by a script) I tried a new el7 snapshot installation during which I switched to tty2 and here, I could observe that /dev/fd is indeed a symlink to /proc/self/fd. So it might have been fixed on this underlying level; some pointers: - early fix in dracut: http://git.kernel.org/cgit/boot/dracut/dracut.git/commit/?id=f2a716d47ccc2e7c7db97b0a11df1213890cf0a5 - however it is also in RHEL-6 branch? http://git.kernel.org/cgit/boot/dracut/dracut.git/tree/modules.d/99base/init?h=RHEL-6&id=f2a716d47ccc2e7c7db97b0a11df1213890cf0a5 - and dracut itself still has issues with process substitution? http://git.kernel.org/cgit/boot/dracut/dracut.git/commit/?id=dba2055979aabc5140ee3e607deed4aa390f4ae1 - 1y+ log showing that dracut was indeed creating the symlink in el7 https://bugzilla.redhat.com/show_bug.cgi?id=829682#c18 Can anybody confirm this issue really happens in el7 tree? I've just tested it and I worked for me. So I'm closing this bug as WORKSFORME. If anybody hits it, please reopen the bug. I also believe that this bug doesn't depend on the RHEL 6 one. Completely agreed, good to see things are better already. Re dependency: this is a feature of "bug clone" (that I am not exactly motivated to fight with) rather than anything intentional. |
