Revision bfe5424a8b31624e7a476f959d552999f931e7c7 authored by Michal Marek on 09 June 2011, 14:35:41 UTC, committed by Michal Marek on 09 June 2011, 21:05:54 UTC
depmod from module-init-tools < 3.13 and the busybox depmod check if the kernel release starts with <num>.<num>.<num>. To support these versions, we create a symlink with two numbers prepended. Signed-off-by: Michal Marek <mmarek@suse.cz>
