I remember this issue I reported earlier here:
http://forum.tinycorelinux.net/index.php/topic,18263.msg111030.html#msg111030"coreutils" and "crda" were imported erroneously, it might be that?
I also agree unsetting the value before could solve the case, anyway I didn't try.
About speed, I do all under virtual machine, that's why I can feel the weight of every instruction there.
I didn't perform any non-functional test of course, because in fact I thought you must have done that already, so just pointed out some options I got in mind.
Clearly, if you already did all tests cases possible, small word, no point in checking that again.
As I said, my efforts were in fact to be focused in disabling (not improving) the prebuilt packs and bed2sce custom scripts access.
I successfully accomplish that, which gave me much higher granularity of options when selecting packages.
I'm happy that my test results are confirming my expectations.
Afaik, both rebuilt packs and deb2sce scripts can be disabled safety, in the case the application works well already without.
In case it doesn't work, it seemed to me, its always matter of a small missing detail, and a look to the deb2sce script helped in finding that detail.
I had the feeling that some scripts and pack actually in use, contain outdated procedures when applied to ubuntu pack, but I might be wrong.
Anyway, something to really keep in mind, came out of my tests: dCore busybox is bugged
And unfortunately the few versions at ubuntu repo, even more bugged!
Apart depmod problem, the cp likes to messup, when dealing with symlink, meaning links get overwritten and targets get lost.
That happen
mostly when loading in different sce, packages belonging to the same functionality, e.g. libs in one sce, the dev in another sce... but not only.
Also that, I didn't investigate further, clearly I'm not going to fix busybox bugs, simply I went by workarounds: pay attention to where put similar debs and don't duplicate them in other sce.
Then, I might have other technical matters to report, but I don't know if you are interested.
