There is no new DTD element required to implement what you are
requesting. As long as you have an ALFS tool that implements
dependencies (which nALFS does not yet), you can do this:
Download whatever BLFS profile you like. That will most likely have a
top-level file called BLFS.xml. Create, in that same directory, a file
called "my-BLFS-config.xml". The contents would be:
<package name="My BLFS Config">
Then, start nALFS as:
nALFS BLFS.xml my-BLFS-config.xml
When nALFS starts, you will see two profiles listed. Ignore the BLFS
one, and open the "my-BLFS-config" profile, and mark it in its entirety
for running. Once nALFS supports dependencies, it will search all loaded
profiles for the packages that were marked as "required", and mark them
as well, and then mark their dependencies and so on, until either
everything needed has been marked, or something that is needed could not
Once the marking is done, hit "s", "m" to run the marked elements, and
only the needed parts of the BLFS profile will be run.
There are some things needed for this to work properly; each package in
the BLFS profile must be entirely independent (i.e. it must not require
any "setup" steps to have been run before it, unless it is marked to
require those steps). This can be achieved without tremendous effort,
and is very easy for the end user to use.
