One can define arbitrary variables in a config file (texmf.cnf) and
each of them can be overwritten by an environment variable. Even more,
a variable foo in a config file can be overwritten by by the envvar
foo and foo_<progname> if <progname> is the string that the program has
given as argument to kpse_set_program_name() during initialization.
$ TEXPOOL_foo=funny; export TEXPOOL_foo
$ tex -ini -progname foo tex.ini
! I can't read tex.pool; bad path?
This invocation of tex has made use of the envvar TEXPOOL_foo (the path
funny is invalid and thus, tex.pool cannot be found).

I strongly suggest that you read the full kpathsea manual (texdoc
