Shadow-4.9

Reference: 8.25. Shadow-4.9. Apply a patch to fix the build system:

patch -Np1 -i shadow-4.9-bld-20220303.patch

Disable program  group  and man pages like in the book:

sed -i 's/groups$(EXEEXT) //' src/Makefile.in
find man -name Makefile.in -exec sed -i 's/groups\.1 / /'   {} \;
find man -name Makefile.in -exec sed -i 's/getspnam\.3 / /' {} \;
find man -name Makefile.in -exec sed -i 's/passwd\.5 / /'   {} \;

Make some default improvements in  login.defs  (this is different as in the book): (: todo: /var/log and more)

sed -e 's:#ENCRYPT_METHOD DES:ENCRYPT_METHOD SHA512:' \
    -e 's:/var/spool/mail:/qlnx/var/mail:'            \
    -e '/PATH=/s|=.*$|="/exec:/qlnx/bin"|g'           \
    -e 's|/etc/|/qlnx/etc/|g'                         \
    -e 's|/var/log/|/qlnx/log/|g'                     \
    -i etc/login.defs

Fix a programming error:

sed -e "224s/rounds/min_rounds/" -i libmisc/salt.c

Do not  touch /usr/bin/passwd  like in the book. Instead apply a patch which fixes (hopefully) all locations in the sources:

patch -Np1 -i shadow-4.9-src-20220314.patch

The patch doesn't touch the install locations pre-defined in  shadow.spec.in .

./configure --prefix=/qlnx \
            --sysconfdir=/qlnx/etc \
            --includedir=/qlnx/inc \
            --with-group-name-max-length=32

Fix the newly created file  libtool :

sed -i 's|/dev/null|/qlnx/dev/null|g' libtool

Unfortunately we have to fix some wrong locations in  config.h  after configure. Apply a patch to do it:

shadow-4.9-qlnx-3-20220314.patch

Build and install shadow:

make
make install

This installs the admin executables in  /qlnx/sbin . We do this temporarily, because it makes the next command to change the access mode easier:

chmod 0750 /qlnx/sbin/*

Last move the files in  /qlnx/sbin  to their final location and remove the directory:

mv -v /qlnx/sbin/* /qlnx/bin
rmdir /qlnx/sbin
