#log into kurobox as root
wget ftp://ftp.kernel.org/pub/linux/kernel/v ... 5.6.tar.gz
tar xvzf 'linux-188.8.131.52.tar.gz'

#copy the config file from Sylver to the linux sources
#before you start menuconfig to do the changes
cp /boot/confighg /usr/src/linux-220.127.116.11/.config

#Device Drivers -> Multi-Device Support (RAID and LVM) -> Device Mapper Support
#Device Drivers -> Multi-Device Support (RAID and LVM) -> Crypt Target Support
#Device Drivers -> Block Devices -> Loopback Device Support
#Cryptographic Options ->
