config BR2_PACKAGE_DCRON bool "dcron" depends on BR2_USE_MMU # fork() depends on BR2_PACKAGE_BUSYBOX_SHOW_OTHERS help dcron is a time-based job scheduler with anacron-like features. It works as a background daemon that parses individual crontab files and executes commands on behalf of the users in question. Upon installation, this package will enable a system level cron daemon with hourly, daily, weekly and monthly crontabs. However, it doesn't allow non root users to create their own crontab file. This is because /var/spool/cron/crontabs is non user writable. Typically, a crontab group is created on the system and users allowed to create crontab entries are added into this group, while crontab executable is owned by root:crontab with sgid bit enabled. http://www.jimpryor.net/linux/dcron.html
