Step 2: Process Substitution not generally supported

[schmidt3d]

Process substitution is not generally supported by all shells. Running Step 2 in busybox on a Synology NAS, I had to use a work around using temporary files.
Maybe it makes sense to change this in order to make the shell code more general?

Sure!

printf "[SAN]\nsubjectAltName=DNS:foo.com,DNS:www.foo.com" >tmp1
cat /etc/ssl/openssl.cnf tmp1 >tmp2
openssl req -new -sha256 -key domain.key -subj "/" -reqexts SAN -config tmp2
rm tmp1
rm tmp2
