My minimal kernel without additional changes shows: -r-xr-xr-x 1 root wheel 2.5M 7 Apr 17:22 /boot/kernel.old/kernel* -r-xr-xr-x 1 root wheel 8.1M 7 Apr 17:22 /boot/kernel.old/kernel.symbol= s* -r-xr-xr-x 1 root wheel 3.9M 24 Mai 18:46 /boot/kernel/kernel* -r-xr-xr-x 1 root wheel 14M 24 Mai 18:46 /boot/kernel/kernel.symbols* But this is with debugging (-g) enabled. How's the .symbols generated? =20 Can there be some new stuff in the kernel which needs to be handled in =20 the .symbols file generation? Bye, Alexander. --=20 The relative importance of files depends on their cost in terms of the human effort needed to regenerate them. =09=09-- T. A.
