** Also affects: cloud-init (Ubuntu)
Importance: Undecided
Status: New
** Description changed:
+ cloud-init docs are not clear that ';' in kernel cmdline is potentially
+ missmarsed by bootloaders, and thus the values passed to ds= should be
+ ideally escaped like ds='all the settings' because \; to separate key-
+ value pairs can be eaten easily. see the below confusing where most of
+ the cmdline after and including ';' got discarded

Attempting to automate the installation of Ubuntu Server 20.04 on a
variety of machines, some that use isolinux and others that require
UEFI+grub2. Booting the installer works fine on all machines tested,
but adding ds=nocloud;s=<path-to-file> and ds=nocloud-net;s=<url> do not
work for machines that boot via UEFI+grub2. These parameters work fine
from the same install media on machines that boot via isolinux. For
ds=nocloud;s=<path-to-file>, custom ISO images were used. Both adding
meta-data and user-data to the cdrom and to installer.squashfs failed
under UEFI, and yet both work fine for isolinux. Also, ds=nocloud-
net;s=<url> failed under UEFI for both the custom ISO images and for the
standard images. Both the release version of 20.04 and the latest
groovy daily build from 2020-05-11 were tested. For test machines that
require UEFI+grub2 automated installation appears to be impossible while
using ds=...;s=... options. Install logs attached. Tests were
performed by inserting an early command: "echo EARLY COMMANDS" into
user-data and then checking the log files for the string "EARLY
COMMANDS". This proved to be sufficient for testing isolinux boots
without the need for a complete installation. For s=<url>, log files
were checked after networking was established.
