So i am trying to write a script for hardening Ubuntu based on CIS benchmarks,this is what recommended for /var:CIS benchmark details
for testing purpose i have installed a new Ubuntu 22.04 in Vbox,findmnt --kernel /var has no output, so /var is not mounted.My question is how do I mount /var as a separate partition, i have tried adding /dev/sda3 /var ext4 defaults 2 2 to the /etc/fstab file and run mount -a command to mount /var , this does not give any error and also shows in the list when i run findmnt --kernel, but when i reboot the system, the OS crashes.
Please help me in implementing this.
