Check whether the current process is running inside a chroot. Currently only supports ext2, ext3 and ext4 file systems.

npm i is-chroot

import isChroot from 'is-chroot'

isChroot()

Behind the scenes isChroot() checks whether the inode of / is exactly 2. If this isn't the case and the file system is ext2, ext3 or ext4 then it's likely that the current process is running inside a chroot. Please note that this is only a heuristic and can be improved by considering additional factors.
