Thank you Chris et al. for your reply.
Even if I told you in my last
mail I had no chanche to investigate further, I took some time to burn
some SD and tried to understand the topic.
Well, in my build machine, 4
packages remain unpacked:
But, since openssh-sshd and update-modules are intentionally
left unpacked (if test "x$D" != "x"; then exit 1 - in the .postinst
script), it seems that for udev and net-snmp-server something goes
Looking in depth, I saw that in udev_141.bb, inside
pkg_postinst_udev_append(), the usual test
if test "x$D" != "x"; then
isn't written before
update-rc.d $OPT udev-cache start 12 S .
this piece of code is not available.
Result: update.rc.d fails in the
build machine because OPT is empty.
Then we have not S03udev and
S12udev-cache init links and S98configure can repair the situation but
only from 2nd boot on.
To solve the problem I had to add that usual
test inside pkg_postinst_udev_append() in udev_141.bb, then bitbake
Similar thing happens for net-snmp-server, where the
postinst script has the same piece of code written twice, resulting in
an error and then in the flag unpacked for the package.
the first occurrance I got good results.
Here net-snmp configuration
by means of S98configure is less dramatical because net-snmp agent
starts after S98configure and then everything is fine also in 1st boot.
I hope this investigation could help someone involved in the same

Yes, this is correct. Some postinsts do things
which can be done at image
creation time on the build machine, but not
all. Those which must *run* the
binaries in the filesystem, for
example, cannot be run at build time, so
must be run at first boot time
on the target.
