I rename the thread to make more sense.

Yup, missing a config file :)
If you run "make -C example" on the host, the Makefile will generate
all the host-tailored vdev config files you'll need (such as
persistent interface naming rules). They will be generated in
example/build/etc/vdev (which can just be copied into /etc).
Once you have your config files generated, you'll need to add "-c
/path/to/config/file" as an argument. I just pushed code to vdevd
that makes it look in /etc/vdev/vdevd.conf, if "-c" is not given (and
if /etc/vdev/vdevd.conf doesn't exist, vdevd should fail with ENOENT
instead of EFAULT).
Also, if you want more verbose debugging output from vdevd, you can
pass "-v" or "-v2" :)
Dear Jude,
There is a minor problem: vdevd dies if /run/vdev doesn't exist.
Since /run is typically a tmpfs filesystem and vdev is certainly meant
to run with root priviledge, it should probably create the directory if
it doesn't exist. For now, I create it by hand and invoke 'vdevd /dev' -
all needed files are in their default locations.
Initialization completes OK, as I can check with option -v2. But,
then the daemon dies after writing the following in /run/dev/vdevd.log:
00571:268737912: [ os/linux.c:1463] vdev_os_init: INFO: '/dev' is

rc = -22
00557:268737912: [ main.c:0208] main: ERROR: device quiesce
failure, child rc = -38
If the error code is -errno then 38 = ENOSYS "function not supported".
I am using kernel 2.6.29 and I don't think kernel netlink support
can be removed.
Maybe the version of musl I use is too old; I'm going to work on
that... or retry with glibc.
