Hi Pete,
...I must admit to never having used wcd myself but the trap looks libc066 related. Is your "unix system" up to date with no older copies hanging around?...
Well, as best as I can tell I am throughly YUM/RPM based, meaning, all the individual DLL based stuff has been migrated to the RPM versions where such releases have become available. The "unix system" appears to be fully functional in my install.
...I note that you have "... replaced multiple HPFS386 partitions with a single JFS boot partition." which I do not think is a good idea. My own experience of JFS boot volumes is that they can be somewhat unreliable - and somewhere on the Arca website HPFS rather than JFS is recommended for boot volumes. My own preference is to use small (2Gb is more than adequate) HPFS boot volumes and have apps/data on larger JFS volumes. Just my thoughts...
This situation is a legacy of my multiple years of OS/2 use. I have always had a single main OS/2 partition where all apps as well as the underlying OS lived. Eventually as the 64Gig HPFS limit was reached I moved my DATA stuff (media, docs, etc) to other partitions. With bootable JFS now available I had a choice of either re-installing all this stuff as per the recommended separate OS & separate APPS structure, or keeping things AS-IS and proceeding. Needless to say, I was looking for the least amount of change (no time) and so kept the AS-IS approach.
You are absolutely right about JFS not being quite ready for prime-time...I'm seeing this first hand, some strange results here, such as for example during boot-up I'm now back to the dreaded WPS 'blue-screen' freeze. Setting JFS cache to something like 128MB occasionally causes my display to go to power saving mode during boot (SNAP video drivers here) and I have to CTL-ALT-DEL. The whole JFS tuning topic is a bit of 'black magic', I've been looking for OS/2 reference info and so far beyond a couple of Warpstock presentations I've only found references to some attempts to port the OpenJFS to our platform.
Yeah, I loved HPFS386 and if it wasn't for that pesky 32-bit limit I'd happily stick with it. But having multiple partitions, lengthy boot-up times, etc, etc just proved to be too much. My thinking is: if the tech you are using ends up being a hinderance, maybe it's time has come and you must look for alternatives? JFS is that alternative I am currently pursuing...
