It has been a while since I've touched hustior but that was because it was working perfectly fine for me. Recently my workflow changed and thus hustior needed two new features: screen support and a permanent home directory.
The screen program failed in hustior since day one. I found out
really quickly that it wants to access /dev/pts and so I mount
binded it into the sandbox. But that didn't work. So I've left it
for good. But now I need screen running in hustior. So I've
restarted my search for a solution and after some time I've boiled
it down to the question "How to run screen in chroot". Then the
answer was pretty simple. There is a devpts filesystem
you have to mount and you need to create a symlink from
/dev/pts/ptmx to /dev/ptmx. To use this you need to provide a config
file with the option ProvideTty set to true.
Permanent home directory:
As a default the home directory is part of a tempfs filesystem. Each
folder you want to see there needs to be specified. Unfortunately
programs like Android Studio or Visual Studio Code use a lot of
files and show strange bugs when only some directories have to be
newly created. So I've created the HomeDirectory option for the
config file. The directory you specify there will be your new home
directory in the sandbox.
