I installed 32 bit tarball 2016.10.26 on my Xiaomi Redmi Note 4 and the Gentoo prefix is running nicely.I have attached some images relating to the Gentoo prefix on Android.When Gentoo environment is launched by the startprefix there is change in values of SHELL and PATH variables. Is the root directory  changed too for successful working of Gentoo prefix?

Kindly guide me for further steps.

Thanks and Regards,

Mishal Roy.
