That would be surprising but it may have happened, as I don’t remember without doubts to have run installworld :/ > Signal 12 is SIGSYS, which means that the program tries to use a syscall > not implemented by the kernel. My guess is that your kernel lacks option > COMPAT_FREEBSD10, and the failing syscall is pipe(2). Indeed I do not have COMPAT_FREEBSD10, because I believed my previous world revision was >302092, as noted by the entry about pipe(2) in UPDATING. Any suggestion on how to fix this? Boot the old kernel, add COMPAT_FREEBSD10 to kernel config, and rebuild/install world and kernel perhaps? Thanks for the help! Matteo
