-3. Installer
-=================
+3. Installer/Infrastructure
+===========================
+
+- safer installation
+  currently we just unpack what is in the tar file, but never check that
+  the contents actually agrees with what is listed in the tlpdb. We not
+  even check that the tlpobj contained in the container agrees with the
+  tlpobj taken from the tlpdb. That allows to ship practically everything
+  in the container, overwritting unrelated files.
+  Also not checked is that unpacking the container does not overwrite
+  files from a different package.
+
+- extend revisions (Master/tlpkg/etc/generalize-revisions.diff)
+  we want: [source:]NNN[.RRR]
+  - source specification for listening the origin
+  - NNN as normal revision number
+  - .RRR to provide various upgrades (think of context providing
+    packages with everyday addint +1 to the revision number they could
+    easily overtake upstream texlive)
+  Question: Do we need the source part at all? Isn't it irrelevant?
+
+- multi-source support
+  I think all that ideas with pinning etc are overkill, since we will not
+  have that many different sources. I propose that we use only revision
+  numbers
+  	NNNN[.RRRR]
+  (without any source specification) and that just the highest package
+  number will be installed.
+
+  To be done:
+  . add support for more than one 
+  	depend location:....
+    lines in the tlpdb
+  . add code to the tlmgr to load all tlpdb from all locations
+  . install just simply the hightest number
+
+  (needs generalize revision patch)
+
+- (Master/tlpkg/etc/installed_avail_archs.diff)
+  currently there is a mess-up wrt to available and installed architectures.
+  We use 00texlive-installation/available_architectures for both the set
+  of installed archs and the set of available archs.
+  That should be better done as follows:
+  00texlive.config:
+	should contain the available_architectures stuff
+  00texlive-installation.config:
+	should contain *instead* installed_architectures stuff
+  and tlmgr should check:
+    localtlpdb/00texlive-installation.config/installed_architectures
+  for what archs are actually installed, and 
+    remotetlpdb/00texlive.config/available_architectures 
+  for what can be installed.
+
+  In the texlive-svn both variables would be initialized to the same thing,
+  while others that don't want to be necessary also runable as is (some
+  third party distribution of modules) should only need to set
+    00texlive.config/available_architectures
 
 - rewrite the installer to use TLMedia instead of the horrible hacks of
   TLUtils.
