 Description   

We need to provide MHS-side scripts at boot time. By "MHS-side" I mean able to use eups to find the right version of software to run. We need this both for root (device drivers) and for the pfs user (for actors).

I'm inclined to do something simple like always calling some /software/boot/bootup.sh as root then as pfs on boot. That can look around using the hostname and username, and return a script if there is one. The only system hooks would be the two calls, and we could use @reboot crontab lines to trigger them.

As it stands:

  • /software/pfs_launch, from the pfs_launch git repo
  • /software/pfs_launch/bin/setups.sh would be used to set up the MHS environment by all users.
  • /software/pfs_launch/bin/launchFor.sh runs ("."s, actually) scripts in hosts/$host_prefix/$user.
  • Only root and pfs-data scripts for non-NIR BEEs have been tested.
  • Fired off with @reboot /software/pfs_launch/bin/launchFor.sh lines for the two users. No system (/etc) files need to be changed.
  • The only override file is a versions.txt in the root /software/pfs_launch directory: keep it visible and simple.
  • Running on b2, as shipped from JHU.

Works OK for booting. Needs to be reshaped so that users can use it too. Basically split into a setup and a run step.

Not awful.

Following SpS software telecon 2019-01-09: Need to move code to an official PFS GitHub repo

The @reboot trick is not working on the temp board pi. Not sure why yet; /software might not be mounted, or the currently necessary X server is not running.

Discussed with arnaud.lefur and Fabrice. Work in progress and expect this to be done before Jun 17. Some work will be done in the interim however.
