FreeBSD crashes (r312349): during installworld and installkernel, the running system crashed and left me with a nullyfied Samsung 850 PRO SSD, means: almost every binary in /bin, /sbin, /usr/bin, /usr/sbin has filesize NULL, execpt /bin/sh. Booting is impossible. Since it is unknown what the crash triggered - I just tried to rescue my box from crashing by adding this faulty EARLY_AP_STARTUP option to my customized kernel - I intend to rescue the system by installing the binaries again via make installworld by using an USB image from the FreeBSD site: FreeBSD-12.0-CURRENT-amd64-20170105-r311461-memstick.img Booting this USB image, mounting all of the filesystems of the SSD of the trunkated system into /mnt (/mnt/usr, /mnt/usr/local etc) execpt /usr/src and /usr/obj, which Imount to the USB's /usr/src and /usr/ob, and then trying to perform the installworld again via cd /usr/src make DESTDIR=3D/mnt installkernel installworld I fail: I'm bothered with the lack of a compilerand enforced to set COM=C3=9CILER_TYPE, but this is useless, since this minimalistic and useless provided USB (and CD image) does obviusly not contain any compiler. So, I'm stranded! I found several websites on which exact such a rescue procedure is explained and I remember that I rescued the same way last year an 11-CURRENT system. At this moment, I can not fathom what kind of mind is behind of the reduction of the images and extracting essential parts. How am I supposed to rescue a system the way I try to? I have an intact /usr/obj, /usr/src, I have this crap USB image wihich is obviously incapable of performing such kind of rescue. The system in question does not have a DVD or CD drive, it is USB only.=20 Any help appreciated. Please point me to the proper webpage on the FBSD site on which it might be to find how to rescue a system like I'm inclined to (if ever). I couldn't find any suitable notices. many thanks in advance, Oliver
