** Description changed:
+ == SRU JUSTIFICATION ==
+
+ IMPACT: its possible, though not all that likely, that files and
+ metadata will be out of sync when systems are shutdown or rebooted after
+ upgrading upstart or any of the libraries it depends on (namely, libc6).
+ Therefore the potential impact is data corruption.
+
+ TEST CASE:
+
Steps to reproduce:
1. Start an Ubuntu 11.10 Oneiric instance on EC2.
Example: ec2run ami-bbf539d2 -t t1.micro -k key
2. Save sudo lsof for reference.
3. apt-cache show upstart
The stock version of upstart installed is 1.3-0ubuntu10.
4. sudo apt-get update; sudo apt-get install upstart
upstart is upgraded to 1.3-0ubuntu11
5. Verify that /var/run/init.upgraded is in fact touched by the install.
6. Save sudo lsof for reference.
7. sudo shutdown -h now
The console displays while unmounting:
- mount: / is busy
+ mount: / is busy
+ This error will not show when the bug is fixed.
+
+ DEV FIX: The problem is that /var/run is cleared out for the transition
+ to /run before the 'init.upgraded' flag file is checked for. The order
+ of operations is changed.
+
+ REGRESSION POTENTIAL: The code path that is changed is very straight
+ forward and tight, just swapping the order of two basic sets of
+ operations. I would consider this to have a low regression potential
+ then.
+
+ =====
This causes filesystem recovery errors on next boot.
The post-upgrade lsof is attached.
