net: add rfc3442 (classless static routes) to EphemeralDHCP
The EphemeralDHCP context manager did not parse or handle
rfc3442 classless static routes which prevented reading
datasource metadata in some clouds. This branch adds support
for extracting the field from the leases output, parsing the
format and then adding the required iproute2 ip commands to
apply (and teardown) the static routes.
templates/ntp.conf.debian.tmpl: fix missing newline for pools
The debian ntp.conf template did not contain a newline for the
comment used to mark the rendered ntp pools configured. This
resulted in an invalid line:
'# poolspool 0.int.pool.ntp.org iburst'
rather than:
'# pools
pool 0.int.pool.ntp.org iburst'
This patch fixes the template and updates the unittest to
verify that the rendered templates puts servers and pools
at the beginning of a line.
Add a cdrom size checker for OVF ds to ds-identify
With a large size ISO file attached to iso dev, ds-identify might
grep it entirely if iso dev is ISO9660, it takes very long time to
start OS.
Resolve this by:
- Adding a checker to read the ISO size (from sysfs). If
the size of the ISO filesystem is > 10MiB then the ISO will be
ignored (logged as oversized).
- Move the ovf vmware guest customization checker to be
ahead of cdrom ovf checker, so no need check the ISO size if vmware
guest customization is enabled.
VMWare: Trigger the post customization script via cc_scripts module.
cloud-init does not trigger reboots of a VM therefore adding custom
scripts to rc.local does not execute the post scripts. This patch
moves post-scripts into per-instance scripts dir and has cc_scripts
module run the post-scripts.
Also in this branch:
- Remove the sh interpreter and execute the customization script
directly.
- Update the unit test.
Cloud-init analyze module: Added ability to analyze boot events.
This branch introduces a new command line feature for cloud-init.
Currently, the cloud-init module has the capability to analyze events in
cloud-init.log in three ways: 'show', 'blame', 'dump'.
These changes add a fourth capability, called 'boot'.
Running the command 'cloud-init analyze boot' will provide the user three
timestamps.
1) Timestamp for when the kernel starts initializing.
2) Timestamp for when the kernel finishes its initialization.
3) Timestamp for when systemd activates cloud-init.
This feature enables cloud-init users to analyze different boot phases.
This would aid in debugging performance issues related
to cloud-init startup or tracking regression.
The current filename, 50-cloud-init.cfg, does not match against the RE
that is used to scan the directory for configurations (ASCII upper- and
lower-case letters, ASCII digits, ASCII underscores, and ASCII
minus-hyphens): https://salsa.debian.org/debian/ifupdown/blob/master/interfaces.5.pre#L122
Of course many installations use `source /etc/network/interfaces.d/*`,
but not all.
