Since systemd 206 the combination of systemd and mkinitcpio
causes, under certain conditions, the rootfs to be double fsck'd.
Symptoms:
```
:: performing fsck on '/dev/sda1'
systemd: clean, 3523/125488 files, 141738/501760 blocks
********************** WARNING **********************
* *
* The root device is not configured to be mounted *
* read-write! It may be fsck'd again later. *
* *
*****************************************************

[ OK ] Started File System Check on Root Device
```
This occurs when neither 'ro' or 'rw', or only 'ro' is present
on the kernel command line. The solution is to mount the roofs
as read-write on the kernel command line, so systemd knows to not fsck
it again.
The extended testsuite only works with UID=0. It contains of several
subdirectories named "test/TEST-??-*", which are run one by one.
To run the extended testsuite do the following:
$ ninja -C build # Avoid building anything as root later
$ sudo test/run-integration-tests.sh
ninja: Entering directory `/home/zbyszek/src/systemd/build'
ninja: no work to do.
--x-- Running TEST-01-BASIC --x--
+ make -C TEST-01-BASIC BUILD_DIR=/home/zbyszek/src/systemd/build clean setup run
make: Entering directory '/home/zbyszek/src/systemd/test/TEST-01-BASIC'
TEST CLEANUP: Basic systemd setup
TEST SETUP: Basic systemd setup
...
TEST RUN: Basic systemd setup [OK]
make: Leaving directory '/home/zbyszek/src/systemd/test/TEST-01-BASIC'
--x-- Result of TEST-01-BASIC: 0 --x--
--x-- Running TEST-02-CRYPTSETUP --x--
+ make -C TEST-02-CRYPTSETUP BUILD_DIR=/home/zbyszek/src/systemd/build clean setup run
If one of the tests fails, then $subdir/test.log contains the log file of
the test.
To run just one of the cases:
$ sudo make -C test/TEST-01-BASIC clean setup run
Specifying the build directory
==============================
If the build directory is not detected automatically, it can be specified
with BUILD_DIR=:
$ sudo BUILD_DIR=some-other-build/ test/run-integration-tests
or
$ sudo make -C test/TEST-01-BASIC BUILD_DIR=../../some-other-build/ ...
Note that in the second case, the path is relative to the test case directory.
An absolute path may also be used in both cases.
Configuration variables
=======================
TEST_NO_QEMU=1 can be used to disable qemu tests.
TEST_NO_NSPAWN=1 can be used to disable nspawn tests.
KERNEL_APPEND='...' can be used to add additional kernel parameters for the QEMU runs.
The kernel and initramfs can be specified with $KERNEL_BIN and $INITRD.
(Fedora's or Debian's default kernel path and initramfs are used by default)
A script will try to find your QEMU binary. If you want to specify a different
one with $QEMU_BIN.
Debugging the qemu image
========================
If you want to log in the testsuite virtual machine, you can specify additional
kernel command line parameter with $KERNEL_APPEND and then log in as root.
$ sudo make -C test/TEST-01-BASIC KERNEL_APPEND="systemd.unit=multi-user.target" run
Root password is empty.
