Dear genteel users,
Recently I'm trying to run Open Genera on Gentoo, which requires the old NFS v2 protocol for communication. I successfully run it on a Ubuntu 16.04 virtual machine, which enables it by default. In 5.18.12 it seems deprecated and not supported, am I supposed to revert back to a kernel version before its removal, or manually patch it into the current kernel ? Or there might be some more elegant methods ? It will be much appreciated if anyone could help :)
