Chad Smith has proposed merging ~chad.smith/cloud-init:host/fixmounterrormatch
into cloud-init:master.
Commit message:
azure: Accept variation in error msg from mount for ntfs volumes
If Azure detects an ntfs filesystem type during mount attempt, it should
still report the resource device as reformattable. There are slight
differences in error message format on RedHat and SuSE. This patch
simplifies the expected error match to work on both distributions.

Resubmitted by Chad Smith in order to rebase on master for a CI test fix
Fixes lp:1799338 by omitting the prefix of the error message from the
text-to-match. This skips the part of the error message that differs between
RHEL and SUSE without introducing a regexp match, which would be needlessly
expensive in this case.
