These are the envs that are passed by the termux openssh to a session.

• HOME=/data/data/com.autosec.pie/files/build/home is incorrectly set. Should be /data/data/com.autosec.pie/files

• SHELL=/data/data/com.autosec.pie/files/build/usr/bin/login login shell does not work for some reason in AutoPie

• changing the login shell manually to bash works.

• chsh does not work because weird path issues due to termux patched chsh.

• LD_LIBRARY_PATH is not set. But that is by design in termux.

• sshd_config needs to hardcode AuthorizedKeysFile /data/data/com.autosec.pie/files/.ssh/authorized_keys. Default config does not work . %h/.ssh/authorized_keys does not work either.

AutoPie switched its folder structure to better reflect termux's so most of the issues here are fixed.

The issue of sshd_config relative paths not working still exists. Which is the default state.
