Hey guys: I was talking to Brian Finley yesterday about the idea of having first(re)boot scripts (Brian pointed out that it is actually first _re_boot, as opposed to firstboot, so we will go with that name now).
We hashed out some ideas and I summarize them below for discussions. Brian, if I got them wrong, please let me know. So basically we wanted to have a set of scripts that are executed on nodes when they are first rebooted after being imaged. This is along the lines of pre-install and post-install scripts. These scripts will reside in /etc/systemimager/firstreboot directory in the image (and subsequently on the imaged node) and there will be a README explaining the syntax as well as scripts with numerically ordered names (so that they are executed in order). There will be a state file (/var/state/systemimager-firstreboot) which will specify the state of execution of these scripts, it will contain the last successfully executed script in the firstreboot/ directory and thus gurantees that each script is successfully executed and also that they won't be executed upon each reboot. We didn't explicitly talked about this yesterday but I presume the user would just drop these scripts in /var/lib/systemimager/scripts/firstreboot and then the scripts will just be copied to the image's /etc/systemimager/firstreboot directory. If you perform a get_clients operation, the state file will be removed from the golden image but the scripts will be left intact such that they will be executed after a node is successfully imaged. Potential uses are to report si_monitor status "rebooted" such that the user can know when an imaged node is up and running, and potentially used by OSCAR for doing some pre-OPM post_installation cleanup per client for packages and such. Hope that this is clear for everyone. Cheers, Bernard ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
