I've already solved the problem - not with the suggested process, but via copying missing libs and files from and identical intact source. After that= , I ran make buildword/buildkernel and was able to successfully install the new system. As I stated before: I already had a complete compiled world and kernel exis= ting in their proper, intact folders (usr/src and usr/obj). There was no need to compile a whole world. Intending to "make installworld" failed, this is the real problem, because = the ISO/memstick images provided lack obviously in the required infrastructure = and so these images are worthless for sophisticated rescue operations - or even such a simple ask as described initially in my posting. I created images on CURRENT of my own - they all lack in the ability of hav= ing the necessary tools aboard. So I consider every image useless for rescue operations except, maybe, the DVD image - but this one is not provided anym= ore. For what reason? Time? Accepted. Space/disk usage? Well, welcome back in the stoneage of computer technology ...=20 I remember faintly that there was a small discussion on the @CURRENT list, = but I didn't realize that the result would be the extraction of the compiler. Just for the record: most servers delivered to us do not have CD/DVD drives anymore - they are outdated and considered an extra these days. Purchasing = 1 GB USB thumbdrives is getting even harder, smallest size my employer provides = now is 2 GB. And most optical drives are DVD. From my point of view - and this = is a personal view - the "standard" is > 1GB so there is no need to break down by force the FreeBSD image (if size is the reason) down to < 800 MB or < 1 GB.= I'd consider having < 2GB the line of standards (2 GB USB mem drive). And for those, with need of very small images, smaller images could be prov= ided as the extra. Thank you very much, kind regards, Oliver
