Public bug reported:
The manual for ssh-keygen claims that by default it will create a key in
~/.ssh/id_rsa
The convention used in /bin/sh (and other shells) is that ~/.ssh/id_rsa
is basically "$HOME/.ssh/id_rsa". So changing $HOME should change where
ssh-keygen writes its key.
But it does not. ssh-keygen seems to use the directory extracted from
/etc/passwd. In this terminal session, I change the value of $HOME to
illustrate this:
$ HOME=/tmp sh
$ cd ~
$ pwd
/tmp
$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/drj/.ssh/id_rsa): ^C
