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. Allan
