Obviously, in the above '... rm ... -rf ...' line, don't just restrict that list of objects to './opt ./media ./srv' : add the others too - i.e. the other items immediately under /mnt/lfs - ** EXCEPT FOR ** './sources' and './tools' . (The '... find ... -delete ...' approach below, is fine as-is; it doesn't need any such additions.) And after the removal, verify that all you have got left under /mnt/lfs are the ./sources and ./tools dirs. > > ; or similarly: > > $ (cd /mnt/lfs && find -P . -xdev -depth \ > ! \( -wholename './sources*' -o -wholename './tools*' \) \ > -delete ) > $ > > > * double-check that you have got the backed-up toolchain from > end of chapter 5, and that you can temp-unpack it to a tempdir > (e.g. ~root/tmp/tmp-unpack-lfs-toolch-end_ch5/ ), and that it looks > OK.
