[Clfs-support] Two questions about CLFS sysroot folder and patch apply

[DELUGE]

I have two questions while reading CLFS Embedded.

(1)
On http://clfs.org/view/clfs-embedded/x86/cross-tools/sysroot.html, when execute the command below which folder should be the current directory in terminal? (Is it ~/ or ${CLFS}/cross-tools/${CLFS_TARGET}/ ?)

“ln -sfv . ${CLFS}/cross-tools/${CLFS_TARGET}/usr”

(2)
On http://clfs.org/view/clfs-embedded/x86/materials/patches.html, after I downloaded iana-etc-2.30-update-2.patch file to ${CLFS}/sources/, what command should I execute to apply this patch?
