The archive grep for 12.04 (precise) is done. I see a bunch of (now outdated) documentation wrt. /dev/cgroup, particularly in the kernel sources and in libvirt. ltp also uses it heavily in its test suite. But aside from that there is no maintainer script, installer, or other thing which would create this fstab entry.
archive grep for 10.04 (lucid) is still ongoing, but I don't expect a match there (there's none so far). So I figure this fstab line was added by some third-party package or manually? Note that in the case of nonexisting fstab entries you are supposed to get a friendly-recovery menu or an emergency shell. This doesn't currently happen, which is perhaps the main issue here? This is being tracked in bug 1471258. ** Attachment added: "precise archive grep for /dev/cgroup" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1460794/+attachment/4425717/+files/cgroup-precise.out -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1460794 Title: boot fails if /dev/cgroup fstab entry is present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1460794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
