From: dchmelik@gmail.com   
      
   As a computer scientist/programmer (CS) whose first other OS in college   
   laboratories (labs) was UNIX/*BSD (official in *BSD documentation) I've   
   used chroot decades but avoid newer similar things especially if not on   
   UNIX.  My only long-time chroot usage was using installers as 'liveCDs'.   
   The basic way was as below but recent years GNU/Linux mounts more & more   
   (some maybe needed for) liveCD-like usage has limits.   
      
     mount -o bind /dev /mnt/dev   
     mount -o bind /proc /mnt/proc   
     mount -o bind /sys  /mnt/sys   
     chroot /mnt   
      
   Now I want to chroot to design/build packages but takes much space I heard   
   overlayfs saves/duplicates all bare OS space: how would one install   
   Slackware in chroot/overlayfs?   
      
   I used to discuss/ask about liveCD-like chroot but most/everyone entirely   
   ignored (what else you need to mount) and threads devolved off-topic   
   mentioning virtual machines & more & more containers (all overkill)...   
   sure, some containers may automate same but (I doubt are that simple and)   
   defeat purpose learning manual UNIX[-like] software so I no longer reply.
