The provisioner will come to rescue once the system boots but as i want to accomplish the custom partitions during the build process, i would like to know how to achieve this. the reason i am asking this is, many organizations doesnt want to have all filesystems under / and more over CIS benchmarks expects to have separate filesystems, so i would like to know how is this being actioned.
