<listitem><para>Generations properly form a tree. E.g., if after
|
|
|
|
|
switching to generation 39, we perform an installation action, a
|
|
|
|
|
generation 43 is created which is a descendant of 39, not 42. So a
|
|
|
|
|
rollback from 43 ought to go back to 39. This is not currently
|
|
|
|
|
implemented; generations form a linear sequence.</para></listitem>

<listitem><para><emphasis>Build management.</emphasis> In principle it
|
|
|
|
|
is already possible to do build management using Nix (by writing
|
|
|
|
|
builders that perform appropriate build steps), but the Nix expression
|
|
|
|
|
language is not yet powerful enough to make this pleasant (?). The
|
|
|
|
|
language should be extended with features from the <ulink
|
|
|
|
|
url='http://www.cs.uu.nl/~eelco/maak/'>Maak build manager</ulink>.
|
|
|
|
|
Another interesting idea is to write a <command>make</command>
|
|
|
|
|
implementation that uses Nix as a back-end to support <ulink
|
|
|
|
|
url='http://www.research.att.com/~bs/bs_faq.html#legacy'>legacy</ulink>
|
|
|
|
|
build files.</para></listitem>

<listitem><para>For security, <command>nix-push</command> manifests

should be digitally signed, and <command>nix-pull</command> should
|
|
|
|
|
verify the signatures. The actual NAR archives in the cache do not
|
|
|
|
|
need to be signed, since the manifest contains cryptographic hashes of
|
|
|
|
|
these files (and <filename>fetchurl.nix</filename> checks
|
|
|

them).</para></listitem>

|

which is hard-coded into <command>nix-env</command>. Also, the

default builder should be more powerful. For instance, there should

be some way to specify priorities to resolve
