init daemon requires mounted /proc subsystem

[Patryk Zawadzki]

...on a booting system.

The chicken and egg problem is that upstart is the first process to run yet it still requires some other process (rc scripts here in PLD Linux) to mount all the directories and set / to be writable.

If it wants to mess with oom_adj / oom_score, it should postpone the adjustments until /proc becomes available.

Or just let the processes keep their current score if they are spawned before /proc is up - most of these are "tasks" to mount the partitions, not real services anyway.

Am waiting for somebody to author a patch for this who is willing to undergo copyright assignment.

[Patryk Zawadzki (patrys)]

What kind of copyright assignment? The simplest solution would be to just warn and ignore the call if proc was not available.

[Scott James Remnant (Canonical) (canonical-scott)]

If there's no OOM adjustment set for the process, it shouldn't be necessary to set it at all - if there is one set, the job should certainly *not* be run since a required parameter is not set.

I'm sorry but I'm not interested in signing that document. It's more than any of my current and past employers required and I'm in no way connected to Canonical. It's nothing personal. We'll just have to wait for someone else to write the patch.

That's unfortunate,

Could I ask which part of the document you object to and you feel is
unreasonable? We attempted to make a very light assignment.

I'm surprised that you feel your employers required more, since unless
I'm mistaken, general employment law means that any work you do while
employed by a company is inherently owned by that company?

I do part of my Free Software contributions at work during office hours. They are happy with my contributions as we are a software shop and use a lot of Free Software so it's natural to give back. On the other hand they don't even ask me to use my company e-mail address (I doubt you can find my place of work in any commit message).

Here in Europe laws do move ownership of the work to the company but the companies are free to assign them back to employees.

As I said, it's nothing personal, keep up the good work :)

Right, and the Upstart copyright assignment also assigns the work back
to you, so you're free to do with it what you will after submission.

Fixed in 0.5.0-3.

[Jeff Oliver (jeffrey-oliver)]

This patch was generated between 2 revs of the job_process.c file in my development branch of upstart.

[Scott James Remnant (Canonical) (canonical-scott)]

Merged Jeff Oliver's fix into trunk http://bazaar.launchpad.net/~scott/upstart/trunk/revision/1110
