Why would your login shell need to be fully POSIX compatible?
This was more of a problem when they didn't support basic POSIX-isms so even basic calls to
shlikesh -c 'echo "foo" && echo "bar"'would fail. Less of a problem now but you never know when a random script is going to rely on some obscure POSIX flagScripts who use
#!/bin/share independent of your login shell.What does any of that have to do with your login shell?
They warn about it on their home page, so I assumed using it could bust your system. My bad.
I think they also had harsher wording about this in the past but I might be misremembering...
