Okay I have had a successful build with the x86_64-64 book regarding  
the changes required to using libblkid from tools for e2fsprogs and  
systemd and moving util-linux after systemd and dbus. And added test  
suite commands for systemd.

Of course we'll need to adjust some commands for the multilib books.

For e2fsprogs:

sed -i -e 's|^LD_LIBRARY_PATH.*|&:/tools/lib|' tests/test_config
LIBS=-L/tools/lib CFLAGS="-I/tools/include" PKG_CONFIG_PATH=/tools/lib/ 
pkgconfig ../configure.........

For systemd:

cat > config.cache << "EOF"
KILL=/bin/kill
HAVE_BLKID=1
BLKID_LIBS="-L/tools/lib -lblkid"
BLKID_CFLAGS="-I/tools/include/blkid"
EOF

sed -i "s:blkid/::" src/udev/udev-builtin-blkid.c   (before configure)

sed -i s:test/udev-test.pl::g Makefile (for a test suite failure  
before make -k check)
make -k check

And then for util-linux after systemd and dbus:

Same commands except this time it'll link against libudev and will  
include addition information for UUID and other output for findmnt and  
lsblk.

You can refer to the LFS systemd branch book and look at ch6 e2fsprogs  
and systemd builds to see what I am talking about for changes  
utilizing /tools/lib/liblkid.  I did also adjust Systemd commands to  
not use LIBRARAY_PATH=/tools/lib make and instead set BLKID_LIBS="-L/ 
tools/lib -lblkid"

For Dbus: I may replace that this package does not have a test suite  
text to state that there is a test suite but requires additional  
packages from cblfs or so. But since cblfs is quite old, I don't know  
if our current version of dbus is the same or needs updated for  
required packages supporting the dbus test suite. I can refer to BLFS  
for that at the moment.

Any suggestions are requested. I plan to make the changes sometime  
today or tomorrow after I test a multilib build.

Sincerely,

William Harrington
