Chapter 4. Base ULFS customization
Prev	Part I. Getting started	Next

If you use pure LFS base you have to perform few operations to ensure ULFS support:

If libffi source package was compiled with "--with-gcc-arch=native" parameter, recompilation with parameter "--with-gcc-arch=x86-64" is required before installing packages on ULFS64. On ULFS32 recompilation with parameter "--with-gcc-arch=i686" is needed.
Source package wget have to be installed.
Chimp script have to be placed in /usr/bin directory
File /etc/profile should like as described in BLFS. http://www.linuxfromscratch.org/blfs/view/8.3-systemd/postlfs/profile.html. You can have a additional directives in that file if needed.

File /etc/profile.d/ulfs.sh should be created to enable ULFS functionality in LFS.

cat > /etc/profile.d/ulfs.sh << "EOF"
export UMVIRT_ASSISTANT_URL=https://umvirt.com/linux/assistant/
export UMVIRT_PACKAGES_URL=https://umvirt.com/linux/packages/
export UMVIRT_RELEASE=0.1
EOF

When steps described above are committed, reboot your system and run "chimp" command without arguments. You have to get message "CHIMP IS READY TO ACCEPT COMMANDS".
