Grumf ! that's annoying :(

Thank you very much for your quick answer ! :)

As I only need the CAP_SYS_BOOT, I will define it manually in the source 
code and will remove the include, that's ugly but anyway... :/

As I understood, the fix in the kernel conflicts with the workaround in 
userspace, right ?
I was wondering if I should notify this to the maintainer of the libcap 
or is it already known ?

Thanks
