Not my business, but how do you handle cases of rand() srand()-like
calls from software like awk?

There are libraries available which provide arc4random() on Linux, so
maybe you find an upstream software provider who is willing to create
a dependency on such a library on Linux.
Lots of software is doing precisely that, so don't be afraid.
Thank you. Are there any specific good

Indeed, if a system has LibreSSL, you will find the arc4random
family in -lcrypto.
