This change allows the vagrant user to see the systemd process in the
event that the hidepid mount option is enabled.
Also adds sudo: true to other tests that use `systemd?`
When checking if the hostnamectl command should be used for configuring
the guest hostname, ensure the command returns a valid result. The
hostnamectl command relies on dbus and if dbus is not available the
command will simply fail.
Use sudo option for communicator test command instead of inline sudo
to properly use configured sudo value. Use command for checking
availability of hostnamectl. Use is-active for determining if a
service is being actively managed by systemd.
If you have a vagrant box with proc mounted with
proc /proc proc defaults,hidepid=2 0 0
ps output will be limited to owned process
sudo should extend output
`vagrant up` may hang at the "Configuring and enabling network
interfaces..." step when private networks and PTY allocation for SSH
are used.
The newer version of `nmcli` that is part of CentOS now will open a
pager (i.e. `less`) for certain commands if it finds a tty. This
causes the invocations of `nmcli` in `guest_inspection.rb` to hang.
`nmcli` disables the use of a pager in 'terse' (`-t`) output mode,
while still returning enough information for the uses in
`guest_inspection.rb`.
Prior to this commit, the regex matcher used with grep to determine if a
system was using systemd? was failing on systems that did not exactly
match the old regex. This commit updates that communications test to use
a different method of determining if systemd is in use with the ps
command.
Properly detects NetworkManager on guest as well as devices controlled
by NetworkManager. Provides configuration option to enable/disbale
NetworkManager control on devices.
