DJB daemontools: compile and install scripts (OpenBSD)

[J65nko]

Introduction

The standard installation of the Daniel J. Bernstein's daemontools software creates some directories in "/".
For many years I just ignored the complaints from others that this is not according the OpenBSD standard file layout as described in hier(7).

However for an installation on a Compact Flash card I needed to be able to specify where the files end up.
The following two scripts try to achieve this:

• new_daemontools_compile
• new_daemontools_install

new_daemontools_compile

#!/bin/sh +e
# $Id: new_daemontools_compile,v 1.4 2009/11/13 02:37:48 root Exp $

DAEMONTOOLS="daemontools-0.76"
DAEMONTOOLS_ARCHIVE="${DAEMONTOOLS}.tar.gz"

NEEDED="${DAEMONTOOLS_ARCHIVE} \
       new_daemontools_install \
       dt-makefile.patch"

for file in ${NEEDED} ; do
   if [ ! -f $file ] ; then
      echo $0 : Sorry cannot find file $file
      exit 1
   fi
   echo "$0: OK found file $file"
done

echo
echo -Unpacking ${DAEMONTOOLS_ARCHIVE}
echo

tar -xpvzf ${DAEMONTOOLS_ARCHIVE}

CURDIR=$(pwd)

cd admin/${DAEMONTOOLS}/src/

echo
echo $0: -------- Patching Makefile
echo

patch -p0 -l Makefile ${CURDIR}/dt-makefile.patch

echo
echo $0: ------- compiling daemontools --------
echo
make ||  exit 100 

echo
echo $0: ----- Compile finished --------
echo You now can run the 'new_daemontools_install' script
echo

After checking if all necessary files are in the current directory, it first unpacks the daemontools tarball. This results in a lot of files under the directory ./admin.

Before running Bernsteins makefile, it is patched with the dt-makefile-patch file, shamelessly stolen from the FreeBSD daemontools port.
