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.
opennebula: exclude EPOCHREALTIME as known bash env variable with a delta
This branch is needed to allow cloud-init to sbuild on Ubuntu Disco.
OpenNebula:parse_shell_config tries to do a comparison of bash
environment values, excluding expected environment variables which
are known to change.
Bash on Ubuntu Disco surfaces a new EPOCHREALTIME environment variable
which wasn't in previous bash environments, this var needs to be
ignored by parse_shell_config too.
run-container: uncomment baseurl in yum.repos.d/*.repo when using a proxy
When using a proxy it is often useful to know in advance which mirrors
are to be contacted, so a whitelist can be set up. This is not easy when
using the yum.conf(5) mirrorlist option, as the retrieved list of mirrors
may change. The repository definition may also specify a canonical mirror
with the 'baseurl' option; this option is often commented out by default
to favor the usage of worldwide mirrors. This patch uncomments 'baseurl'
when an http_proxy is being used, so the canonical mirror is used *in
addition to* the mirrors retrieved from the mirrorlist.
