Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=24699501
|
||||
Upstream: RHEL-only (upstream doesn't ship systemd units)
|
||||
|
||||
Hyper-V daemons' units are udev activated: when the appropriate device
|
||||
appears systemd unit is started and normal targets (e.g. multi-user.target)
|
||||
don't depend on these units. With systemd it is possible to try to isolate
|
||||
the target (somewhat similar to switching runlevel), this is supposed to
|
||||
shut everything which the target doesn't depend on (like units started
|
||||
manually) off. It seems that the general users' expectation is that
|
||||
hyperv-daemons units survive the procedure.

|

- Only start kvpd under Hyper-V.
|
||||
|
||||
- Minimize dependencies for kvpd by removing the unnecessary
|
||||
network.target requirement, but add kvp device and mount
|
||||
requirements.
|
||||
|
||||
Start before cloud-init-local.service which relies on kvpd
|
||||
for Azure.

RH-Commit: [1/1] 2887e0ad51a16a499ebdeac29f3086c8be481e0c (anisinha/centos-hyperv-daemons)
|
||||
|
||||
It is incorrect in python to compare integer values using the "is" keyword. The
|
||||
"is" keyword in python is used to compare references to two objects, not their
|
||||
values. Newer version of python3 (version 3.8) throws a warning when such
|
||||
incorrect comparison is made. For value comparison, "==" should be used.
|
||||
|
||||
Fix this in the code and suppress the following warning:
|
||||
|
||||
/usr/sbin/vmbus_testing:167: SyntaxWarning: "is" with a literal. Did you mean "=="?
