Since commit b7e7184 the SysV generator creates symlinks for all "Provides:" in
the LSB header. However, this is too greedy; there are cases where the
creation of a unit .service file fails because of an already existing
symlink with the same name:
- Backup files such as /etc/init.d/foo.bak still have "Provides: foo", and
thus get a foo.service -> foo.bak.service link. foo.bak would not be enabled
in rcN.d/, but we (deliberately) create units for all executables in init.d/
so that a manual "systemctl start" works. If foo.bak is processed before,
the symlink already exists.
- init.d/bar has "Provides: foo", while there also is a real init.d/foo. The
former would create a link foo.service -> bar.service, while the latter
would fail to create the real foo.service.
If we encounter an existing symlink, just remove it before writing a real unit.
Note that two init.d scripts "foo" and "bar" which both provide the same name
"common" already work. The first processed init script wins and creates the
"common.service" symlink, and the second just fails to create the symlink
again. Thus create an additional test case for this to ensure that it keeps
working sensibly.

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:
$ make all
$ cd test
$ sudo make clean check
...
make[1]: Entering directory `/mnt/data/harald/git/systemd/test/TEST-01-BASIC'
Making all in .
Making all in po
Making all in docs/libudev
Making all in docs/gudev
TEST: Basic systemd setup [OK]
make[1]: Leaving directory `/mnt/data/harald/git/systemd/test/TEST-01-BASIC'
...
If one of the tests fails, then $subdir/test.log contains the log file of
the test.
To debug a special testcase of the testsuite do:
$ make all
$ cd test/TEST-01-BASIC
$ sudo make clean setup run
QEMU
====
If you want to log in the testsuite virtual machine, you can specify
additional kernel command line parameter with $KERNEL_APPEND.
$ sudo make KERNEL_APPEND="systemd.unit=multi-user.target" clean setup run
you can even skip the "clean" and "setup" if you want to run the machine again.
$ sudo make KERNEL_APPEND="systemd.unit=multi-user.target" run
You can specify a different kernel and initramfs with $KERNEL_BIN and $INITRD.
(Fedora's default kernel path and initramfs are used by default)
$ sudo make KERNEL_BIN=/boot/vmlinuz-foo INITRD=/boot/initramfs-bar clean check
A script will try to find your QEMU binary. If you want to specify a different
one you can use $QEMU_BIN.
$ sudo make QEMU_BIN=/path/to/qemu/qemu-kvm clean check
