The default root shell is not /bin/ksh but /bin/sh on NetBSD

[tsutsui]

README.md says:

The default shell in NetBSD is ksh, if you want to use sh to execute the run script, please set usesh to true.

However the default root shell has been /bin/sh since NetBSD 6.0: https://github.com/NetBSD/src/commit/a1da65bdfb8783a1da69f02917eb858477115152

Change root's default shell to /bin/sh, to provide a default which has command line editing, tab completion, and other features users have come to expect from a modern OS.

Discussed on current-users approximately two weeks ago. Should be pulled up for NetBSD 6.0.

On the other hand, OpenBSD actually uses /bin/ksh for root: https://github.com/openbsd/src/commit/850c97e0fd6ce968556a6698cd0c0d6a78172c35

change root login shell to ksh as promised; ok many

Note it looks FreeBSD has changed the default root shell to /bin/sh since FreeBSD 14: https://github.com/freebsd/freebsd-src/commit/d410b585b6f00a26c2de7724d6576a3ea7d548b7

sh(1): make it the default shell for the root user

In the recent history sh(1) has gain the missing features for it to become a usable interractive shell:

• command completion
• persistent history support
• improvements on the default bindings in emacs mode
• improvements in the vi mode (repect $EDITOR)
• print a newline when exiting via ^D
• default prompt and improvements on how PS1 can be configured
• and more.

This changes also simplifies making tiny freebsd images with only sh(1) as a shell

Anyway, it looks run.sh should invoke ssh with -t to make sure ~/.profile is loaded, otherwise we have to explicitly set PATH environment for commands in /usr/pkg/sbin etc.
