Sort of. 2.6.x set's 2.6 mode, and everything else is 2.4 mode. But this is AFAIK only a semantic change of some functions. This does not disable syscalls which are in 2.6 but not in 2.4. > but what happens when compat.linux.osrelease gets set to a different > value? ports/Updating entry 20071101 e.g. advises skype users to set > compat.linux.osrelease to 2.4.20. does this trigger 2.6 > kernel-emulation because 2.4.20 > 2.4.2 or are there more than two > kernel-emulation layers inside the linuxulator?? It does not affect the kernel emulation. But the glibc will try to use new syscalls. Bye, Alexander.
