Successes and failures at inf.ed.ac.uk

  • Components don’t seem to be reconfiguring when they get a change of resources. I had to “om boot configure” to get it to pick up changes to boot.services that were made days ago, despite several reboots since the change. I also just had to “om cron configure” to get the cron component to process a new cron job I’d added to its resources.
  • inf/options/ntp.h was configuring /etc/ntpd.conf but that was all. It now starts ntpd too by adding rc_ntpd to boot.services.
  • Have been having difficulties with the cron component. Then spotted that inf/os/f12.h was still removing it from profile.components and boot.services. Oops. Now removed those removals; lcfg-cron and crond now start correctly on reboot.
  • I’ve worked out some things that lcfg-sleep needs in order to work on F12:
    • F12 versions of perl packages, including two which aren’t in the Fedora distribution and had to be got from CPAN (perl-DateTime-Event-Cron and perl-DateTime-Format-Epoch)
    • The newer kernel means a change to using the newer kernel alarm file /sys/class/rtc/rtc0/wakealarm instead of /proc/acpi/alarm. This is what needs perl-DateTime-Format-Epoch.
    • Removal of suspend-time and resume-time actions for LCFG components not currently in use on F12 (lcfg-ntp and lcfg-amd).
      I’ve slept the test F12 machine and woken it several times and so far it’s behaving wonderfully: nice quick wake-ups and no video problems at all. We’ll see tomorrow how the sleep component performed overnight.
  • I spotted that xemacs didn’t have a full complement of packages by the fact that it was missing a perl mode. I’ve added them to lcfg_f12_base.rpms where the other xemacs packages were put a week or two ago.
