after this, I actually got systemd-208, not udev-208, so I just
cd systemd-208 instead.

Everything went well till test/udev-test.pl

FAIL: test/udev-test.pl
=======================


udev-test will run 137 tests:

TEST 1: no rules
device '/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda' expecting node/link 'sda'
failed to mount empty /usr/lib/udev/rules.d No such file or directoryadd:         error
Can't exec "tree": No such file or directory at ../test/udev-test.pl line 1444.

failed to mount empty /usr/lib/udev/rules.d No such file or directoryremove:      ok

...

TEST 137: builtin path_id
device '/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda' expecting node/link 'disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0'

Can't exec "tree": No such file or directory at ../test/udev-test.pl line 1444.

failed to mount empty /usr/lib/udev/rules.d No such file or directoryremove:      ok

135 errors occurred

finally ended with:

==== test-utf8.log ====
goo goo goo
����
��
make[1]: *** [override_dh_auto_test] Error 1
make[1]: Leaving directory `/home/qhuang/systemd-208'
make: *** [build] Error 2
dpkg-buildpackage: error: debian/rules build gave error exit status 2



Is this because the tests failed? I don't have /usr/lib/udev/rule.d but I have
/lib/udev/rule.d

Or is the precess right that build the whole systemd? Is there a way I can
build and install only udev?

Thanks.
