That is not so straightforward, because the directory $link might as
well be created during '6.5-Creating directories'. We do not want to
remove it in that case. And if (as is the most probable) we stay with
a subdirectory of /run, it is harmless, since the bootscripts mount
a tmpfs on /run.

I hope I have taken care of all those in LFS/master.sh. In HLFS, and 
CLFS, it is for another version
of the book, where I do not think they have done any change (HLFS is 
dormant and CLFS
does not have the changes yet).
