[Buildroot] Is there a working version of opkg?

[Grant Edwards]

Does anybody know of a working verison of opkg?  I've tried 0.6.2 and
0.7.0, and both versions have a file-locking bug. The basic 'opkg'
utility appears to fork off multiple children (WHY?!?!?) which then
collide with each other when trying to lock /var/log/opkg.lock.

It can be plainly seen using strace, but to make it a little more
obvious, I added fprintf() calls to opkg_lock/unlock:

    # opkg install --force-reinstall --force-downgrade <foo>.opk
    
    PID 843 PPID 696 opkg_lock()
    Installing <foo> on apps.
    beginning preinst...
    PID 846 PPID 844 opkg_lock()
    error: opkg_lock: Could not lock /var/run/opkg.lock: Resource temporarily unavailable.
    error: opkg_cmd_exec: Command failed to capture privilege lock: Resource temporarily unavailable.
    ending preinst.....
    Configuring web-server.
    beginning postinst...
    starting /apps/webserver...
    ending postinst...
    PID 843 PPID 696 opkg_unlock()

If found some old threads discussing the addition of waits/retries
when acquiring that lock but that "solution" was apparently rejected
in favor of just leaving it broken.
