I tried it by manually editing .config. but make oldconfig warns: WARNING: unmet direct dependencies detected for PROC_SYSCTL Depends on [n]: PROC_FS [=n] Selected by [m]: - MPLS_ROUTING [=m] && NET [=y] && MPLS [=y] && (NET_IP_TUNNEL [=n] || NET_IP_TUNNEL [=n]=n) * * Restart config... * * * Configure standard kernel features (expert users) * Configure standard kernel features (expert users) (EXPERT) [Y/?] y Multiple users, groups and capabilities support (MULTIUSER) [Y/n/?] y sgetmask/ssetmask syscalls support (SGETMASK_SYSCALL) [N/y/?] n Sysfs syscall support (SYSFS_SYSCALL) [N/y/?] n Sysctl syscall support (SYSCTL_SYSCALL) [N/y/?] (NEW) Regards, -- Matteo Croce per aspera ad upstream
