That doesn't really explain anything, what does it really do?

echroot extends the basic options that we found in chroot, with echroot
we can control many more options than executing chroot. Here I show
some of the options that we can happen to echroot.

For example: 

mkdir ~/MOUNT

Mount another linux partition in ~/MOUNT
mount /dev/sda1    ~/MOUNT

with chroot
--->  chroot ~/MOUNT   /usr/bin/mc     
Run mc of   /dev/sda1   in  root   

 
with echroot
--->  echroot  --user=YOURUSER  --group=YOURGROUP  --stderr=YOURFILE  ~/MOUNT /usr/bin/mc 
Run mc of /dev/sda1   in root and set the UID of the process to YOURUSER,  the GID of the process to YOURGROUP, redirect STDERR to YOURFILE, etc .... 


The output of man echroot command.
