Re: [ptxdist] Opkg status file in initrd

[Ariel Garcia <a.garcia@gemfony.eu>]

Hi,

thanks a lot for your answer.

It works now, i only had to fiddle a bit to find the right path variables...
genimage does not seem to export any for exec-pre commands (in particular TMPPATH 
used internally) so had to resort to a not-so-nice shell glob
  ${PTXDIST_TEMPDIR}/genimage.*/root/usr/share/opkg


For future reference, the end result is:

-----------
$ cat configs/platform-name/config/images/cpio.config

image @IMAGE@ {
    exec-pre = "rm -rf ${PTXDIST_TEMPDIR}/genimage.*/root/usr/share/opkg ; \
                touch -r ${PTXDIST_TEMPDIR}/genimage.*/root/usr {PTXDIST_TEMPDIR}/genimage.*/root/usr/share"
    cpio {
        format = "@FORMAT@"
        compress = "@COMPRESS@"
    }
}
-----------

Greetings
