Summary

By default, the bzip2(1), gzip(1), and progress(1) binaries are located in /usr/bin. By default they dynamic linked against /usr/bin/libz.so.0.1 and /usr/lib/libbz2.so.1 and /usr/lib/libc.so.12

Unfortunately, /usr/lib/libz.so.1.0 is actually a symlink to /lib/libz.so.1.0 while /usr/lib/libbz2.so.1.0 is a real file.

Additionaly (netbsd-4 ex.) /usr/lib/libc.so.12 is a symlink /lib/libc.so.12.149

$ ldd /usr/bin/gzip

Problems

Problem 1: /usr/bin/gzip and /usr/bin/bzip2 must be moved into /bin so that

they can be exec()'d by pax(1) during rc(8).

Problem 2: If the binaries are moved from /usr/bin to /bin, the flist

mechansism will "miss" them when generating release tarballs

Problem 3: The new binaries must link against /bin/libc, /lib/libz, and /lib/libbz

direct instead of their counterparts in /usr/lib/

Problem 4: The binaries bzip2 library cannot be a symlink from /lib/ to /usr/lib,

instead the actual binary must be located in /lib and an optional symlink from /usr/lib to /lib can exist for compatability. This will make it like libz.

Problem 5: The new libraries build and installed into /lib instead of /usr/lib,

the flist mechanism will "miss" them when generating release tarballs

Problem 6: /usr/bin/progress must be available as well. It must be located in

/bin and must be linked against /lib/libc instead of /usr/lib/libc

Solutions

Problem 1 & 2 - Solution

The binaries must be manually copied from $DESTDIR-DATE_CODE to $DSTDIR/bin where the base.tgz and etc.tgz release binary tarball sets are extracted

Proposed Solution: The flists could be modified, but that's on ongoing local working copy CVS conflict that could be dangerous. Perhaps conditional'izing in the flists using MK{FLAG}

Problem 3 - Solution

Setting the following:

    SHLINKDIR=     /libexec
    SHLIBDIR=       /lib

src/usr.bin/progress/Makefile +

and src/usr.bin/gzip/Makefile +

and src/usr.bin/bzip2/Makefile

in:

Will cause the binaries to link against /lib instead of /usr/lib, however the install-path for the binaries will remain unchanged.

  /home/nbsd/dst.i386/20070304-2031EST/usr/bin/bzip2:
        -lbz2.1 => /lib/libbz2.so.1
        -lc.12 => /lib/libc.so.12

Problem 4 - Solution:

Setting the following:

    SHLINKDIR=     /libexec
    SHLIBDIR=       /lib

in:

src/lib/libbz2/Makefile

Will cause libbz2 to install into /lib instead of /usr/lib. /usr/lib will receive the appropriate symbolic links:

Problem 5 - Solution

The libraries must be manually copied from $DESTDIR-DATE_CODE to $DSTDIR/lib where the base.tgz and etc.tgz release binary tarball sets are extracted

Proposed Solution: The flists could be modified, but that's on ongoing local working copy CVS conflict that could be dangerous. Perhaps conditional'izing in the flists using mk.conf(5) flags that could be submitted upstream.

Problem 6 - Solution

Partially solved by Solution #3. Manual copy required.

# cd $src_dir
# ./build.sh -T tool.i386/${datecode} -D dst.i386/${datecode} \ 
    -R rel.i386/${relcode} -O obj.i386/${datecode} release

# mkdir dstdir_extr_pruned && cd $!
# pax -r -pe -z -f rel.i386/${relcode}/i386/binary/sets/base.tgz
# pax -r -pe -z -f rel.i386/${relcode}/i386/binary/sets/etc.tgz
# du -hs .
  56m .
# cd foo/dst.i386/${DATECODE}/lib && pax -rw -v -pe libbz2* foo/dstdir_extr_pruned/lib && cd -
# cd foo/dst.i386/${DATECODE}/usr/bin && pax -rw -v -pe progress bzip2 gzip foo/dstdir_extr_pruned/bin && cd -
# cd .. && ldd ./bin/*zip* ./bin/progress && ls -alF ./lib{,/usr}/lib*z* 

For example:

export DSTDIR_TMP=/home/nbsd/dstdir
export relcode=20070304-2031EST

cd $DSTDIR_TMP
pax -r -pe -z -f /home/nbsd/rel.i386/${relcode}/i386/binary/sets/base.tgz
pax -r -pe -z -f /home/nbsd/rel.i386/${relcode}/i386/binary/sets/etc.tgz
du -hs .

cd /home/nbsd/dst.i386/${relcode}/lib && pax -rw -v -pe libbz2* ${DSTDIR_TMP}/lib && cd -
cd /home/nbsd/dst.i386/${relcode}/usr/bin && pax -rw -v -pe progress bzip2 gzip ${DSTDIR_TMP}/bin && cd -
cd ${DSTDIR_TMP} && ldd ./bin/*zip* ./bin/progress && ls -alF ./lib{,/usr}/lib*z*
