Setting up the machinery to boot with the aid of real networked boot loader
(such as iPXE) would involve much hassle, including possibly serving the kernel
and initrd via TFTP, etc.
Let us generate the iBFT table ourselves, with a Perl script. Include the
pregenerated table as well so that the test run won't depend on Perl. In the
end it's just reproducibly built static data, totally independent of the host
system.
New systemd defaults to generating MAC addresses for software devices (whereas
previously they would inherit them from the first enslaved slave).
Sadly, among the things this breaks is our test fixture, where the dhcp servers
are configured to expect a particular MAC address. Disable this for the
affected tests, which are essentially the ones that use bridges and bonds.
The network interfaces appear asynchronously and sometimes just too late,
after we're already halfway throught server-init.sh:
+ ip link set dev eth0 name ens3
Cannot find device "eth0"
+ ip addr add 192.168.50.1/24 dev ens3
Cannot find device "ens3"
+ dhcpd -cf /etc/dhcpd.conf -lf /var/lib/dhcpd/dhcpd.leases ens3 ens5
...
[ 8.040825] e1000 0000:00:03.0 eth0: (PCI:33MHz:32-bit) 52:54:01:12:34:56
[ 8.047105] e1000 0000:00:03.0 eth0: Intel(R) PRO/1000 Network Connection
...
No subnet declaration for ens3 (no IPv4 addresses).
** Ignoring requests on ens3. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface ens3 is attached. **
Whoopsie. Let's ensure all the interfaces are there before we proceed
fiddling around with them.
This change still supports Python 2.6 and 2.7 but loses support
for Python 2.5.
The reason for this change was that Fedora 30 does not ship
python-imgcreate but ships python3-imgcreate.

If the network-manager plugin is used instead, it wouldn't write out
ifcfg files and we wouldn't have anything to check.
While at that, also enable the test.
The IFCFG test will make sure the network-legacy plugin keeps writing
out correct ifcfg files.
This is a separate commit so that actual changes are visible in the
following one.
On Fedora 30 the paritition sizes turn out to be too small again:
+ mkdir -p /sysroot
+ mount /dev/dracut/root /sysroot
+ cp -a -t /sysroot /source/bin /source/dev /source/etc /source/lib /source/lib64 /source/proc /source/root /source/sbin /source/sys /source/tmp /source/usr /source/var
cp: error writing '/sysroot/usr/lib64/libkrb5.so.3.3': No space left on device
cp: error writing '/sysroot/usr/lib64/libkrb5support.so.0.1': No space left on device
It turns out that there has been quite some size increase in some libraries,
notably glibc, though not all -- some even shrunk, ruling out a toolchain
problem. Here's are files over 1M we install on Fedora 30:
f29 f30
2.7M => 6.4M /usr/lib64/{libc-2.28.so => libc-2.29.so}
3.1M => 6.0M /usr/lib64/libcrypto.so.1.1.1c
2.0M => 3.5M /usr/lib64/{libm-2.28.so => libm-2.29.so}
2.9M => 2.8M /usr/lib/systemd/{libsystemd-shared-239.so => libsystemd-shared-241.so}
1.7M => 2.5M /usr/lib64/libunistring.so.2.1.0
2.3M => 2.4M /usr/lib64/bind9-export/libdns-export.so.1105.0.0
1.2M => 2.1M /usr/bin/bash
1.1M => 1.4M /usr/lib64/libkrb5.so.3.3
1.2M => 1.4M /usr/lib64/libgcrypt.so.20.2.4
612K => 1.1M /usr/lib64/libssl.so.1.1.1c
This increases the image sizes to accomodate for this. There's probably
little else we can do.
The dracut-root-block-created line should not be created if we fail to copy
in the required files to sysroot. Let's turn on -e to trap failures and
poweroff on them, like some other tests do.
Also remove the &&. Not only it is unnecessary with -e, but defeats it.
From bash(1):
The shell does not exit if the command that fails is [...] part of any
command executed in a && or || list except the command following the
final && or || [...]
