Aargh - I did two things at the same time

1. patch attached in previous mail
2.
$D${sysconfdir}/rcS.d/S${POSTINSTALL_INITPOSITION}run-postinsts


Now that I reverted 2. pango is again not properly prepared after
first boot :( So it is not a matter of wrong configuration of opkg by
meta-angstrom.

Seems that writing output of 'opkg-cl configure' changes timing and
thereby working around the bug.

Suspicious: The systemd startup sequence log says:

and

root@overo:~# journalctl | grep tmp
Aug 20 16:59:33 overo S98run-postinsts[68]: * opkg_prep_intercepts:
Failed to make temp dir /tmp/opkg-07xOYO/opkg-intercept-wfVgAQ: No

Aug 20 16:59:56 overo kernel[276]: devtmpfs: initialized
Aug 20 16:59:59 overo kernel[276]: devtmpfs: mounted

So my conclusion (for now): During postinst /tmp is required (by which
package I don't know and guess it is out of interest). Unfortunately
at that time /tmp is not yet mounted causing postinst to abort and
leave packages undone:

Support running postinst after /tmp is mounted is welcome...
