I saw your message last night, but it was a little bit late for me so I promised to myself to be the first thing to do today. So here it is, a little more than you expected. :) For the rest. We are talking about dash, which is a standard POSIX shell, quite useful for debugging and very light/small shell that can be used in small systems. >From what I've read Dash (Debian's Ash) is maintained by Herbert Xu from Debian, who was also the Ash maintainer. So since Ash is not longer under development, I am proposing to drop Ash for Dash. As a first step, I created a patch to include Dash into the Book - I didn't commented out the Ash page. Dan, I didn't applied the debian patch since from what I've saw it's debian specific stuff (correct me if I am wrong). I also placed the dash binary into /bin, which seems a natural choice, plus debian do the same. I also make use of the --mandir, since the default location is $PREFIX/man. This is only for FHS compliance. I didn't create any symbolic link to /bin/sh either. I also found that if I was running 'LANG=C make', I had the same problem with yours [1], so I changed to 'LC_ALL=C make' and now it seems to works properly. So, ff there is no objection I would like to see it in the Book. Dan or anyone else, feel free to make your adjustments to the patch, I will be grateful to correct any mistakes. 1. http://linuxfromscratch.org/pipermail/alfs-discuss/2007-February/009135.html P.S Randy, If you want I can create a ticket for it, although for some easy stuff like this I prefer the flexibility of the mailing list.
