Hi,
I thought I'd run this past people on this list before I spent the
two weeks that this would take me to figure out how to implement it!
This is motivated by experience packaging for Arch. Install
scriptlets are written assuming /bin/sh is bash, which is true on a
default system. But some people want to change their /bin/sh to
(e.g.) dash. As pacman uses the default shell (as given by /bin/sh)
to run install scriptlets, pointing /bin/sh at dash may cause
failures when bash specific features are used.
So I thought, why not manually specify the shell for install
scriptlets in pacman.conf. Something like "INSTALL_SHELL=/bin/sh" by
default. Then _alpm_runscriptlet would call something like "<shell>
-c ".<scriptlet path> && <function>" (which works for bash, dash,
zsh, pdksh).
Comments?

Hi Allan,
can't we use shebangs instead of inventing our own which-shell-to-use
implementation? (#!/bin/sh, #!/bin/bash, ..)
No we can not unless I am missing something. We need to source the
script and run a particular function within that script.
