[02:49] <mgorbach> Very strange. How come sometimes I see logging from upstart on TTY7, and sometimes it's completely empty?
[02:50] <mgorbach> Seems to work about 30% of the time on each reboot of this server machine.
[09:31] <xnox> mgorbach: wait.... maybe it didn't come up yet. tty7 upstart job needs to start and it's racing in parallel with pretty much everything else =)

[15:43] <tseliot> hi all, if I wanted to make sure that a job such as the following doesn't start unless a file is available, would I simply have to test the existence of this file and exit 0 if the file doesn't exist? http://paste.ubuntu.com/6546310/
[15:43] <tseliot> or is there a better way (also compatible with precise)
[15:47] <tseliot> xnox: ^
[15:49] <xnox> tseliot: which file are you testing for?
[15:49] <xnox> tseliot: in general if it's the executable binary "/usr/bin/nvidia-persistenced" simply do
[15:49] <tseliot> xnox: the actual binary /usr/bin/nvidia-persistenced
[15:49] <xnox> tseliot: right, in that case simply do: exec /usr/bin/nvidia-persistenced --user nvidia-persistenced
[15:50] <tseliot> xnox: so, I let it fail?
[15:50] <xnox> tseliot: upstart will notice that the exectuable is not there, and the job will never start and move to stop/failed state. Which is equivalent to any other reasons job may fail to start or not suppose to start.
[15:50] <xnox> tseliot: if you wish you can do
[15:51] <tseliot> xnox: if that's acceptable, then it saves me the effort to work around it
[15:51] <xnox> tseliot: pre-start [ ! -x /usr/bin/nvidia-persistenced ] && { stop; exit 0 }
[15:51] <xnox> tseliot: pre-start exec, but that's entirely redundand.
[15:51] <xnox> tseliot: yeah, that's absolutely acceptable, after all all packages can be removed, but not purged and hence init files left around.
[15:52] <xnox> tseliot: upstart was designed for debian/ubuntu like systems ;-)
[15:52] <tseliot> xnox: I'll keep it as it is then, thanks a lot :)
[15:52] <xnox> =)
[17:15] <tseliot> xnox: so, apparently if that file is a link to the binary, upstart won't use it
[17:16] <xnox> tseliot: can you send / point me to the sample packages?
[17:18] <tseliot> xnox: it's this one https://github.com/tseliot/nvidia-graphics-drivers/tree/331-updates (the 331-updates git head)
[17:19] <tseliot> xnox: and these two patches on top of it: http://paste.ubuntu.com/6546735/ http://paste.ubuntu.com/6546738/
[17:21] <tseliot> and the actual error in /var/log/upstart/nvidia-persistenced.log is "/bin/sh: 1: exec: /usr/bin/nvidia-persistenced: not found"
[17:21] <tseliot> the file is there though, it's a link
[17:22] <tseliot> it's a link because it shouldn't show up and/or run when we disable the discrete nvidia card and use only the integrated Intel card on systems with hybrid graphics
[17:33] <xnox> tseliot: why are you using variables?
[17:33] <xnox> tseliot: do you need it to be configurable / overridable?
[17:33] <tseliot> xnox: in the job? That comes from nvidia
[17:34] <xnox> tseliot: why is your job "exec $VAR", instead of "exec nvidia-persistenced"
[17:34] <xnox> tseliot: with $VAR you are forking a shell, with "exec nvidia-persistenced" i gets directly execed without a fork to a shell.
[17:35] <xnox> tseliot: i'm nearing end of day and still have a few things to finish off.
[17:35] <tseliot> xnox: that's something that I take straight from the nvidia-installer. I can replace with my own upstart job if needed
[17:35] <tseliot> (I didn't write it myself)
[17:37] <tseliot> xnox: no problem, thanks for your help
[17:37] <xnox> tseliot: can you try: http://paste.ubuntu.com/6546826/
[17:37] <tseliot> xnox: nvidia-persistenced is a daemon BTW
[17:37] <xnox> tseliot: =)
[17:38] <tseliot> xnox: oh, I failed to mention that if I start the job manually it seems to work
[17:38] <xnox> tseliot: so how do you start it that makes it fail?
[17:39] <xnox> tseliot: or how does it get started to fail?
[17:40] <tseliot> xnox: start on runlevel [2345]
[17:40] <tseliot> when that happens, I get the error
[17:40] <xnox> tseliot: try my job and reboot.
[17:41] <tseliot> xnox: I think I know where you're getting at ;) Let me try
[17:41] <xnox> tseliot: rm the /var/log/upstart/nvidia*.log first, to make sure you are not looking at old messages.
[17:41]  * xnox been there, done that.....
[17:41] <tseliot> :)
[17:53] <tseliot> xnox: I'm not even getting a log now... weird
[17:53] <tseliot> and it doesn't start
[17:53] <tseliot> unless I do it manually
[18:02] <xnox> tseliot: weird. I'll look into it tomorrow.
[18:02] <tseliot> xnox: thanks :)
