Let take a look at Linux sources, /usr/src/linux-2.6.35/init/main.c:
204: char * envp_init[MAX_INIT_ENVS+2] = { "HOME=/", "TERM=linux", NULL, };
857: run_init_process("/sbin/init");
817: static void run_init_process(char *init_filename)
818: {
819: argv_init[0] = init_filename;
820: kernel_execve(init_filename, argv_init, envp_init);
821: }
As we can see HOME=/ and TERM=linux are provided for init and this might be
expected on some systems (Gentoo comes to my mind, here ;-)). That's why we
should give to init the same set of env. vars as Linux kernel does.
