NAME
emerge-later - Intelligent scheduling for Gentoo's emerge.
DESCRIPTION
emerge-later is a tool that allows you to emerge a package when system is inactive, eg. when you are away from the machine. emerge-later registeres scheduling requests with chronicd, an intelligent scheduling daemon that measures system activity, among other things.
If chronicd isn't running, emerge-later will print a warning. Just start chronicd, and the task will be picked up correctly.
OPTIONS
emerge-later accepts the following command line options:
-
email specifies an email address of the person who should be notified when the emerge is completed. eg. email=admin@example.net
- constraint
-
By default, set to Inactivity, 1200, which implies the task should be scheduled after 20 minutes (1200 seconds) of Inactivity. To learn more about Chronic constraints, please see chronicd(1).
EXAMPLES
emerge-later sys-devel/binutils
emerge-later -email=mail@vipul.net sys-devel/binutilsCHRONIC INTEGRATION
As an example, emerge-later sys-devel/binutils will add the line constraint = Inactivity, 1200; only_once = 1; command = emerge sys-devel/binutils to /etc/chrontab and send a SIGHUP to chronicd(1) to force reload of /etc/chrontab. emerge will be run when the system has been idle for more than 20 minutes (1200 seconds).
