In Gentoo, when you SSH into a system, the environment is typically set up by various shell configuration files. These files are executed when a user logs in and can be used to set environment variables, aliases, and perform other customizations. The specific files executed can depend on the shell being used by the user. Here are some common examples:

1. Bash (Bourne-Again SHell):

When you log in, the system typically runs /etc/profile, which sets up system-wide environment variables and configurations. For each user, when they log in, ~/.bash_profile, ~/.bash_login, or ~/.profile (in that order of precedence) is executed, depending on which file exists and is readable. These files can be used to customize the user's environment. Zsh (Z Shell):

2. For Zsh, the system-wide configuration file is usually /etc/zsh/zshenv. For individual users, ~/.zshrc is typically sourced when they log in, and it's a common place to set user-specific environment variables and customizations. Fish (Friendly Interactive SHell):

3. In Fish, when you log in, the system typically runs /etc/fish/config.fish, which sets up system-wide configurations. For each user, ~/.config/fish/config.fish is executed, and this file can be used for user-specific environment customizations. These are just some of the common configuration files. The exact setup might vary depending on how your system is configured, and you can also customize these files to meet your specific needs. When you SSH into a Gentoo system, these files help to establish your environment, including setting environment variables, aliases, and other shell-related settings.
