> This is all fine with a custom OS, not when it is maintained by a
package manager. Inconsistencies between the different filesystems on
which the package manager operates will just make it mad. Your OS may
still be usable but not updatable. I have realized this after two
decades of crazy partitionning. /home should definitely be separated and
well protected (RAID where possible, backups), /usr/local (or /local)
may as well, /opt also,since Debian does not use it. But the part of the
OS (which is managed by dpkg) better stays on one single partition.
/run, /tmp are well on tmpfs. An efficient way to secure the OS is to
clone it on another partition.
