Description Chen Qi 2013-07-22 02:09:10 UTC 
Now the NSS recipe is added to OE-core, it has a postinst which cannot succeed at rootfs time.

pkg_postinst_${PN} () {
    if [ -n "$D" ]; then
        exit 1
    fi
    signlibs.sh
}

Please figure out a way to do this, or we should remove this postinst, as signlibs.sh is not a requirement for LSB.

Create checksum file at rootfs time to support read-only rootfs.

Test Case:

*On host:
1) In local.conf
    IMAGE_INSTALL_append = " nss"
2) Build core-image-sato

*On target:
1) Search checksum file
root@qemuarm:~# find /usr/lib/ -name "*.chk"
/usr/lib/libfreebl3.chk
/usr/lib/libnssdbm3.chk
/usr/lib/libsoftokn3.chk

2) Test for valid checksum files.
root@qemuarm:~# chktest /usr/lib/libfreebl3.so
SUCCESS
root@qemuarm:~# chktest /usr/lib/libnssdbm3.so 
SUCCESS
root@qemuarm:~# chktest /usr/lib/libsoftokn3.so
SUCCESS
