I use libedit. I am used to NetBSD sh; dash is similar, derived from the same source. I wanted dash to behave more like NetBSD sh, so I changed it. Anyway, I am not a huge fan of "packages". (The problems described in this thread are one reason why.) Of course I use packaged binaries in some instances, but normally I only install them when needed, use them and then uninstall them when I am done. I prefer to compile the kernel and userland myself. That includes the shell. Simply compiling dash with libedit does not provide tabcompletion. Need to make some small changes.
