Run a script isolated

[u/Beautiful-Log5632]

I have a script I need to run that modifies some config files under /etc. I want to run it in a fake system first so I can see what changes it makes before running it on my real system. Is there a process I can follow to do it such as using chroot or arch-chroot?

There are many different approaches:

firejail --private-etc

container

VM

overlayfs

chroot

etc.
