netinfo: Adjust ifconfig output parsing for FreeBSD ipv6 entries
FreeBSD ifconfig output for ipv6 addrs doesn't find scopeid values
when present in the output and the pformat rendering assumes that
an ipv6 address will have a 'scope6' entry in the netdev info
dictionary. This patch finds the scopeid value, which is not
always inside <>, and in some cases v6 addrs don't have a scopeid
value in the output, so when rendering the table, allow scope6 value
to be replaced with the empty value.
netplan: Don't render yaml aliases when dumping netplan
Cloud-init rendered netplan with duplicate aliases if a network config
included "global" nameserver/search values. Netplan uses can read yaml
files which do use aliaes but cloud-init did not render a single yaml
dictionary, instead it combined yaml sections into a single document
which sometimes resulted in duplicate aliases being present.
This branch introduces a yaml SafeDumper class which can set the
'ignore_aliases' attribute. This is not enabled by default but callers
to util.yaml_dumps can pass a boolean to toggle this. The netplan
render uses noalias=True and the resulting yaml output does not contain
any aliases.
opennebula: also exclude epochseconds from changed environment vars
In addition to EPOCHREALTIME there is also an EPOCHSECONDS environment
variable that OpenNebula needs to exclude as it is expected to change.
This commit supplements the other exclusion in commit
d1a2fe7307e9cf2251d1f9a666c12d71d3f522d6.
Without this fix, unittests will intermittently fail if
parse_shell_config is run across a timing boundary where the
EPOCHSECONDS changes mid-test.
systemd: Render generator from template to account for system differences.
The systemd generator used had a hard coded path for the location target
file to create. This path does not apply to all distributions.
Make the generator and template to have the path set during build time.
