811316 - update panda live boot squashfs image

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: General, task)

Description

[Dustin J. Mitchell [:dustin] (he/him)]

I've found a few problems so far:

* mobile-init.sh sleeps for 30s when it begins.  There's no comment to indicate why this would be useful.  Can we remove it?

* It would be great to send a lifeguard event when mobile-init.sh starts

* More worryingly, the rsyslog config file uses ntp.build.mozilla.com, rather than ntp.build.mozilla.org, which causes rsyslog to not start, which causes mobile-init to not start.

*slight* correction to point 3: the bogus hostname does *not* cause rsyslog to fail.  Omitting syslog-server= *does* - my error.

Comment 2

[Dustin J. Mitchell [:dustin] (he/him)]

Another fix:

 * use PST timezone, at least as long as everything else is running in PST

Comment 3

[Dustin J. Mitchell [:dustin] (he/him)]

Two more:

 * panic() doesn't quote the log argument correctly, so instead of "second-stage.sh returned non-zero", you just get

  Nov 13 16:45:52 panda-0045 mobile-init.sh: second-stage.sh


 * it'd be great if this would log the error output of second-stage.sh in this case

These are all baked into the live boot squashfs file, not the preseed image.  I'll also add some documentation as to unpacking/editing/repacking the squashfs.

Comment 5

[Dustin J. Mitchell [:dustin] (he/him)]

Oh, silly me.  And bonus, because that's easier to change!

Comment 6

[Dustin J. Mitchell [:dustin] (he/him)]

* We'll also need a full Python

Comment 7

[Dustin J. Mitchell [:dustin] (he/him)]

* We'll also need uboot-mkimage or (perhaps better) u-boot-tools

Comment 8

[Jake Watkins [:dividehex]]

New sqaushfs has been compiled with the following changes:
* changed timezone to US/Pacific
* install python2.7
* install curl
* install u-boot-tools (mkimage)
* changed ntp.build.mozilla.org in pre-syslog.sh
* mobile-init.sh: properly quotes argument
* mobile-init.sh: logs second-stage.sh err output on non 0 exit
* mobile-init.sh: removed 30 sleep

Changes still needed:
* Lifeguard event needed for mobile-init.sh

I'm at an airport and just didn't have time to add this last one in.  I can add it in on the second pass.

Looks good!  I've installed this (with the old image in /tmp on releng-puppet1.srv.releng.scl3), and will submit a patch to take out my workarounds in bug 812251.

Comment 10

[Dustin J. Mitchell [:dustin] (he/him)]

I just copied this over the existing squashfs, but it occurs to me that we should be pointing to the datestamped version using the PXE configs, so that we can test and revert if necessary.  Next time!

[Jake Watkins [:dividehex]]

per dustin via irc: the Lifeguard event will be "mobile_init_started"

Comment 12

[Dustin J. Mitchell [:dustin] (he/him)]

Some tweaks to mobile-init.sh in bug 816732, too

Comment 13

[Jake Watkins [:dividehex]]

mkdosfs needs to be installed.  bug 817832

Comment 14

[Jake Watkins [:dividehex]]

Attachment: lifeguard event call added

Adds lifeguard event mobile_init_started to mobile-init.sh

Comment 15

[Jake Watkins [:dividehex]]

FTR:  I've uploaded a new squashfs ( precise-panda-live-build.2012120401.squashfs ) with the double ntpdate calls fixed (bug 816732) and mkdosfs installed.  This DOES NOT include the mobile-init.sh patch in c#14.

lifeguard event call added

I like this.  The code duplication is annoying, but necessary in this case.

Comment 17

[Jake Watkins [:dividehex]]

New squashfs is uploaded: precise-panda-live-build.2012120602.squashfs

* updated cltbld passwd
* added lifeguard event "mobile_init_started"
* mobile-init.sh waits for ntpdate to adjust time before starting

All active pxe configs have been updated to the new squashfs.
