I rename the thread to make more sense.

     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 
not on devtmpfs
00571:268737912: [      os/linux.c:1206] vdev_linux_context_init: ERROR: 
socket(PF_NETLINK) rc = -38
00571:268737912: [     os/common.c:0128] vdev_os_context_init: ERROR: 
vdev_os_init rc = -38
00571:268737912: [          vdev.c:0308] vdev_start: ERROR: 
vdev_os_context_init rc = -38
00571:268737912: [          main.c:0152] main: ERROR: vdev_backend_init 
rc = -38
00571:268737912: [          vdev.c:0579] vdev_stop: ERROR: vdev_wq_stop 
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.
