:)To be more precise, there should be no need to change anything in 
/stage1 after chrooting in Chapter 6. That way once the /stage1 
directory is prepared, it can be burned to a CD and reused.

:-) Yep, those were my first impressions, am still working thru it one 
by one, perl is at the far end, and considering the horsepower of my 
CPU, the word "far" really means "far":) BTW, I install perl statically 
using the following configure options.

    ./Configure -d -e -s -Doptimize="$CFLAGS" -Dprefix=/static
    -Dldflags="-s -static" -Dso=none -Uinstallusrbinperl -Uusedl

Yep, but it will only be used till the Ch 6 binutils is compiled which 
is immediately after glibc.

The only affected package would be glibc, since in the hint, the spec 
file is changed immediately after glibc is installed. glibc anaways uses 
its own linker flags to use /lib/ld-linux.so.2 even though gcc specifies 
/stage1/lib/ld-linux.so.2. So, it would be non-issue.

Thanks to you and Ryan for the hint and giving us the opportunity to 
have some fun:) I will be trying the suggestions I mentioned, especially 
the last one.
