According to https://launchpad.net/ubuntu/oneiric/+package/fcron it seems that there is a version of fcron available for 11.10, but reffering to http://www.ubuntuupdates.org/packages/show/329892 it seems that fcron was removed from the repos. Also I cant find it in synaptics.
Is there an easy way to install fcron side by side with cron via PPA? If possible I would be happy if I could avoid selfcompiling it.
