1574	How to meassure SBUs on Cross-LFS	manuel@…	lfs-book@…	"Due that in the new cross-lfs books is possible to build the temp tools on a  
different machine than the final system, we can't use any more the first  
package builded in the book as SBU unit (the Cross Binutils at ""Constructing  
Cross-Compile Tools"". Well, actually the first in cross-lfs is  
Linux-Libc-Headers). 
 
Then, I see this roads: 
 
.- To remove SBUs. I don't agree but is a possibility. 
 
.- To use two SBUs: one for temp tools, based on Cross Binutils, and another  
for final system, based on ???? (see below). 
 
.- To remove SBUs for temp tools. Measure SBUs only for final system packages  
based on the build time for the first package builded after the reboot/chroot  
step. That is my preferred way. 
 
That package is Tcl installed in /tools. Currently in LFS-SVN the SBU for Tcl  
is 0.9. In BLFS-SVN is 0.28 + 0.73 for the test suite. Thus making mandatory  
to run the test suite on Tcl we can have a SBU unit very similar (if not  
identical) to the current one."	defect	closed	highest		Book	Branch_Cross-LFS	major	invalid
