[Bug 606373] Re: cloud-init output does not get to console when booted with pv-grub and ramdisk

[Scott Moser]

Per Andy's advice, I removed the closing of the file descriptors in the
wrapper script (attaching here), and rebooted.

The output is in the ec2 console output looks like:

| [    0.676065] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)

| done.

The interesting output information there is that the missing data is replaced by 'mountall: Disconnected from Plymouth'.

Given that, Keybuk suggested looking in /var/log/boot.log.  It contained
the missing messages.

I then ran:
sudo sh -c 'for x in /etc/init/plymouth*.conf; do mv $x $x.disabled; done'

and rebooted.

The rebooted console log contained all the data.

So, we're looking squarely at plymouth at the moment, not repeating data
to the console.
