getent queries the system resolver for the hostname - but it's not
the resolver we're interested in. In fact, the hostname-to-be-set
may already exist in DNS (becuase DNS really is a nifty thing and
can do a lot of things which are not that possible with /etc/hosts
alone), in which case getent will "not fail" and vagrant will believe
the hostname had already been set.
Instead, query hostnamectl for the "static" hostname - that's the
one we will be setting, so we're ok IFF hostnamectl returns exactly
what we would be setting.
- nfs.service got recently removed in openSUSE Tumbleweed and calling service
restart nfs errors out on Tumbleweed. nfs.service has been an alias to
nfs-client.target for a very long time and can thus be safely substituted.
- all actively supported versions of openSUSE & SLE are using systemd now
=> no reason not to use systemctl
This fixes a fairly large tempfile leak. Vagrant uses a template
renderer to write network configuration files locally to disk. Then,
that temporarily file is uploaded to the remote host and moved into
place. Since Vagrant is such a short-lived process, GC never came along
and cleaned up those tempfiles, resulting in many temporary files being
created through regular Vagrant usage.
The Util::Tempfile class uses a block to ensure the temporary file is
deleted when the block finishes. This API required small tweaks to the
usage, but provides more safety to ensure the files are deleted.
In order to get a SUSE guest running and installing fine i have added a
correct capability for installing rsync and nfs-client.
I have included SUSE naming fixes as well because SUSe doesnt get
spelled SuSE anymore :).
When using pty=true, removing files using sudo may request confirmation,
which will hang the connection.
Similarly, sometimes assumptions about file existence may be wrong and
in those cases it seems better to continue on as long as the file does
not exist, so -f makes sense there, too.
I don't use `activated` here because I'd really like to optimize
performance as much as possible, and loading files from disk is
generally slow. So instead of using `activated` I load the file at the
last possible moment which is when the exact class is being requested.
I don't think many people will do this outside of the core, and I'm not
too concerned.
