[oe] Create dir with 700 permissions from recipe

[s hakkesteegt]

Hi,

For a recipe I want to use locally to enable public key authentication on my
images, I'm trying to create the .ssh dir with 700 permissions. But this
doesn't seem to work. It ends up in the rootfs and in the ipk with 775
permissions, although in the work dir it has the correct 700 permissions.
This is the recipe I created:


SRC_URI=" \
                    file://authorized_keys \
       "

FILES_${PN}=" /home/root/.ssh \
                       /home/root/.ssh/authorized_keys \
           "

do_install(){
       install -m 0700 -d ${D}/home/root/.ssh
       install -m 0600 ${WORKDIR}/authorized_keys
${D}/home/root/.ssh/authorized_keys
}


On irc was suggested to use postinst script. So I tried to add the next at
the end of the recipe.:


pkg_postinst_${PN}-chmodsshdir () {
        chmod 700 /home/root/.ssh
}


1. Do I understand it correct that this postinst script will run on the
target machine (after first boot)? Or is that wrong?

2. This doesn't seem to work either. Am I doing something wrong and is there
a better / right way to add my public key my created images.


Thanks in advance for a reaction,

Siebren
