Namely, calling opkg yields the error " * opkg_conf_load: Could not create lock file /var/lib/opkg/lock: No such file or directory."  I can see that the folder /var/lib/opkg was not created on my filesystem.  If I create this directory and then call "opkg list-installed", I get an empty list back.

If I follow the instructions in Yocto's quick-start-guide and perform
a simple build of core-image-minimal using today's master and make
almost no changes to the configuration (other than to switch to ipk),
the resulting image:
- will not contain the opkg tools
- will have an empty /var/lib/opkg directory (this directory exists,
but is empty)

Build Configuration:
BB_VERSION        = "1.19.1"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "openSUSE-project-12.3"
TARGET_SYS        = "arm-poky-linux-gnueabi"
MACHINE           = "qemuarm"
DISTRO            = "poky"
DISTRO_VERSION    = "1.4+snapshot-20130801"
TUNE_FEATURES     = "armv5 thumb dsp"
TARGET_FPU        = "soft"
meta
meta-yocto
meta-yocto-bsp    = "master:9de0ad47462c13ac4a2d73e12e92be6c1b4e0415"

If I then modify the configuration to add "package-management" to the
EXTRA_IMAGE_FEATURES variable and rebuild, the resulting image:
- will have the opkg tools
- will have a non-empty /var/lib/opkg directory
- I can issue a command such as "$ opkg list" and get:

When I perform these same steps using dylan, it does not work

Build Configuration:
BB_VERSION        = "1.18.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "openSUSE-project-12.3"
TARGET_SYS        = "arm-poky-linux-gnueabi"
MACHINE           = "qemuarm"
DISTRO            = "poky"
DISTRO_VERSION    = "1.4.1"
TUNE_FEATURES     = "armv5 thumb dsp"
TARGET_FPU        = "soft"
meta
meta-yocto
meta-yocto-bsp    = "dylan:899e5cca99ec952ff72c81b74a731150841122f4"

Without "package-management" in the configuration opkg is not
installed in the image (as expected). However, with
"package-management" in the configuration the opkg tools are installed
in the image, but /var/lib/opkg is still empty and the "$ opkg list"
command returns empty.
