[OpenIndiana-discuss] Shell to use?

[Hung Nguyen Gia]

Unfortunately, pkgsrc requires a POSIX shell so dash can't be used. They stated very clear on system with dash as /bin/sh, the user has to export SH=/bin/bash in order to have a successful bootstrap. Later the value of sh which is /bin/bash was carried into mk.conf, too.
