I'm just starting, so may be off base here -
after trying a few different distros, I decided to just use the Live CD, only to find out it is no longer being maintained/updated for LFS 7.5 (???why???)
After doing about 30 searches, I came across Salix 13.xx, and ended up with Salix 14.1
It is small, and lightweight even in it's basic GUI install (a no-gui install is possible as well as a "full" install) - and it meets all of the requirements of the Host System Requirements as found in LFS 7.5 Preface vii, with no tweaking needed (no links to dash, etc.)
Hope this helps someone, although it probably needs to be moved somewhere...
