One of the other things that init.sh does it to iterate over
a few shell names, trying each in turn. If it finds one that
is good enough, it re-execs with that:
# Search for a shell that meets our requirements.
for re_shell_ in __current__ "${CONFIG_SHELL:-no_shell}" \
/bin/sh bash dash zsh pdksh fail
do
...
So, with "bash" somewhere in his PATH, using init.sh
would have found it.
