Evgeny Vereshchagin 24a01950a3 tests: stop using nobody in test-udev.pl (#8239)
`nobody` is a special user, whose credentials should be extracted with
`get_user_creds`. `getpwnam` called in `test-udev.pl` is a bit different,
which causes the test to fail with the following error:
```
device '/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda' expecting node/link 'node'
  expected permissions are: nobody::0600
  created permissions are : 65534:0:0600
permissions: error
add:         ok
remove:      ok
```
The ideal fix would probably be to implement `get_user_creds` in Perl, but in this
PR the issue is simply got around by using `daemon` instead of `nobody`.

Closes https://github.com/systemd/systemd/issues/8196.

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  # Avoid the "sudo make" below building anything as root
$ 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
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 or Debian'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
