To begin with: You install normally chapter 5. Everything goes under /tools, 
no other dirs created or needed. Then chroot and create the directory 
structure, FHS-like. Just after that you mount the desired partitions under 
each dir and continue normally.

As far as sizes are concerned, I usually proceed as follows: I make an 
installation under a singe partition (apart from /boot) of sufficien size. 
Then, after it is complete, I do a "du -sch /dir". This gives the size of the 
/dir in Megs. I note down the info obdained that way for all dirs that wil be 
hosted in a seperate partition. I partition the HDD with a desired scheme, 
following the info obtained; that's it! Of course, you take into 
consideration the variation (usually growing) of the amount of data over 
time. Again you must estimate these values based on expected usage. If you 
plan to do a standard install and use nothing more than a bse system and X, 
only choose wisely the size of /home. The rest directories should not change 
much. A standard exception is /var, that holds the logs which always grow. I 
think it is not possible to provide standard figures for an install, apart 
for the sizes that result from a standard buld of (S)LFS. Its up to the user 
to cater for his future needs. Possible suggestions should be a seperate 
/boot, /home and possibly /var, to face disk space overwhelming from users. 
Guess the magic word is "quota", but partitioning offers better control. More 
to follow (have to dig up some documentation)
