If it is possible, should be pretty basic, but I am puzzled how to ask Google the right question (or it is impossible).
Lets say we have
/home/user/ ...conf /home/user/candidate/ ...conf
We have homedir and some subdir.. programs will use naturally from homedir(
What I need is to temporarily change home user to
*/home/user/candidate*, so programs will call
Now, I don't need usermod or anything else to change permanently
/etc/passwd, i want to temporarily force programs to use my directory, thinking it is home, but on reboot fetch
*/home/user* and act normal.
*/home/user/candidate* as home only session long, no usermod stuff.
