Binary package hint: mountall
As reported at [1], mountall is eating cpu cycles on reboot of both 10.04 (images 20100923 and later) and 10.10.
I believe the issue is related to changes made under bug 634102.
Here is what happens:
- The images are created with an fstab like:
| proc /proc proc nodev,noexec,nosuid 0 0
| LABEL=uec-rootfs / ext4 defaults 0 0
- On first boot, cloud-init writes additional entries like:
| /dev/sda2 /mnt auto defaults,nobootwait,comment=cloudconfig 0 2
| /dev/sda3 none swap sw,comment=cloudconfig 0 0
- On reboot, mountall will be eating CPU. and /mnt will *not* be mounted.
- removing the 'nobootwait' flag, and rebooting will result in system functioning properly
I've modified /etc/init/mountall and added '--debug' and '--verbose', and rebooted and collected the console log.
I believe the issue only presents itself when the device exists at boot and the 'nobootwait' flag is present.
I can boot 2 different instance types,
m1.small : has /dev/sda2 and /dev/sda3
t1.micro : does not have /dev/sda2 or /dev/sda3
mountall will spin in m1.small, but not in t1.micro.
I'm attaching the output of debug boot on m1.small (where /dev/sda2 does exist and mountall spins).

==== SRU Information ====
- Impact: On EC2 or UEC, due to how cloud-init writes fstab entries, on first reboot mountall will eat all CPU cycles. On other systems, a user who updates /e
c/fstab seemingly correct will have mountall spin the first time it runs.
- How it was addressed: Logic error in cut_options routine in mountall was fixe
. The code segment was easily removed and tested against different strings to verify no regressions.
- Patch: A branch has been linked with the same patch as used in maverick.
lp:~smoser/ubuntu/lucid/mountall/bug649591
- How to reproduce:
Edit an existing entry in /etc/fstab for which there is an existing device. Change the options field to contain 'nobootwait,' in front of what was previously there. Reboot. You will now see mountall consuming resources.
- Regression: The most likely regression would be either failure of mountall to mount a device or segfault in mountall. That said, the patch was tested well, and Collin had a strong understanding of the cause.
