test: Embed script for dhclient(8) in mbuto(1) profile

2022-07-13T23:31:28+00:00

David reports that dhclient-script(8) on Fedora needs a number of
binaries that are not included in PROGS of the current mbuto profile,
and we would also need to include hostnamectl(1) there, which will
fail without a systemd init.

Embed a minimal script for dhclient(8) in the profile itself, written
to /sbin/dhclient-script at boot, to just check what we need to check
out of DHCP and DHCPv6 functionality.

While at it, drop busybox and logger from PROGS, as we don't need them,
and add hostname(1). While DHCP option 12 isn't supported yet by the
DHCP implementation in passt, we should probably add it soon.

Note: owing to the simplicity of this script, we now need to bring up
the interface before starting dhclient: add this in test scripts where
it's not the case yet.

Tweak dhclient arguments for readability

2022-06-15T07:38:10+00:00

A number of tests and examples use dhclient in both IPv4 and IPv6 modes.
We use "dhclient -6" for IPv6, but usually just "dhclient" for IPv4.  Add
an explicit "-4" argument to make it more clear and explicit.

In addition, when dhclient is run from within pasta it usually won't be
"real" root, and so will not have access to write the default global pid
file.  This results in a mostly harmless but irritating error:
    Can't create /var/run/dhclient.pid: Permission denied
We can avoid that by using the --no-pid flag to dhclient.

Don't abbreviate ip(8) arguments in examples and tests

2022-06-15T07:38:10+00:00

ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of
"link show") is very handy when using it interactively, but it doesn't make
for very readable scripts and examples when shown that way.

test/two_guests: Fix sleep command for DAD

2021-10-21T18:10:23+00:00

An inline comment prefixed by a space doesn't mean the space
is dropped, and sleep(1) will get a blank in its argument.

Move the comment on its own line.

test/two_guests: Let the guests end DAD before starting the DHCPv6 client

2021-10-21T15:54:03+00:00

They'll start DAD as we bring up the interface, and the DHCPv6
client might be unreasonably delayed if we start it too early.

Not really quick, definitely dirty.
