Well, maybe i am wrong, but for doing a binary update everythin is almost laid, at least that's how i am trying to make it, this is the general approach i am gonna take:
- the client contact the server and ask to see if a profile is available, let the profile be FreeBSD-4.7-RELEASE then asks for a certain "distribution", let' the distribtuion be doc.
- The client now request the doc.aa, doc.ab, doc.?? chunks from the server, the server get them from their location on disk and send them to the client using sendfile(2) as Murray suggested.
- Happilly the client get the chunks then checksum them and follow a silimar approach to install them (i.e: cat doc.?? | tar --unlink -xpzf - -C ${DESTDIR:-/}) as the current sysintall binary update procedure does.
As i said before, correct me if i am wrong but this an "It Works" way of doing it
, but i may be wrong about this is the way the project wants to do it. Please correct me if i am wrong and expect patches by the next week.
