Package: debian-policy Version: 3.5.7.0 Severity: normal In 11.4:
You may wish to restrict your script to POSIX features when possible so that it may use `/bin/sh' as its interpreter. If your script works with `ash', it's probably POSIX compliant, but if you are in doubt, use `/bin/bash'. Debian's ash seems to be renamed to dash now. I suggest changing the clause to "with `posh' or `dash'", since posh is less forgiving of POSIX incompatibilities.
