[oe] R: Re: S98configure role

[l.bolognini at tiscali.it]

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:
openssh-sshd
net-snmp-server
udev
update-
modules

But, since openssh-sshd and update-modules are intentionally 
left unpacked (if test "x$D" != "x"; then exit 1 - in the .postinst 
script), it seems that for udev and net-snmp-server something goes 
wrong.
Looking in depth, I saw that in udev_141.bb, inside 
pkg_postinst_udev_append(), the usual test
if test "x$D" != "x"; then

        OPT="-r $D"
else
        OPT="-s"
fi
isn't written before 
update-rc.d command:
update-rc.d $OPT udev-cache start 12 S .
Simply, 
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 
udev again.

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.
Commenting out 
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 
problems,
bye,
Luca

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.
