kernel-modules-hook-reflink

2 | 3 | **-reflink** is forked from [the original hook](https://github.com/saber-nyan/kernel-modules-hook). 4 | It uses `cp --reflink` to copy modules, saving time and space for Btrfs. 5 | 6 | --- 7 | 8 | Tired of missing modules when updating the kernel?
9 | Annoyed by `modprobe: FATAL: Module smth not found in directory /lib/modules/new-kernel`?
10 | Losing uptime after reboots due to kernel update? 11 | 12 | *The solution is here.* 13 | 14 | * Save.
