   We need more people to improve it!

   chroot, but better

   

   As a number of comments have noted, there are a bunch of different axes that chroot could be 'better' on - e.g. security and sandboxing.

   I wrote https://github.com/aidanhs/machroot (initially forked from bubble wrap) a while ago to lean into the pure "pretend I see another filesystem" aspect of chroot with additional conveniences (so no security focus). For example, it:

   1. allows setting up overlay filesystems

5. bocker

   4 42 12,634 0.0 Shell

   Docker implemented in around 100 lines of bash

   

   I found this project an interesting example of how it all actually works

   https://github.com/p8952/bocker

   Basically, this project runs docker containers inside a chroot environment.

   Docker uses Layered Filesystems (Multiple Filesystems mounted under the same folder on top of one another), something that used to be mostly used to have a read only Filesystem, like a cdrom, then mount a writeable folder over the same mount point to make that folder writeable.
