The following kernel parameters are supported:

aif aif=True do the same thing. if aif is False, it behaves as if aif is not specified. Enable AIF.
|
||||
aif_url path to install XML document. can be e.g.: http://domain.tld/aif.xml https://domain.tld/aif.xml ftp://domain.tld/aif.xml file:///tmp/aif.xml (note that local filesystem references are in relation to the system running the client) (note: HTTPS must be signed by a valid root CA)
|
||||
aif_username the username to use for HTTP/HTTPS Basic auth, HTTP/HTTPS Digest auth, or FTP/FTPS auth (must be specified to use Basic/Digest auth)
|
||||
aif_password the password to use for HTTP/HTTPS Basic auth, HTTP/HTTPS Digest auth, or FTP/FTPS auth (must be specified to use Basic/Digest auth)
|
||||
aif_auth either 'basic' or 'digest', for HTTP/HTTPS auth (ignored for other types). default, if others are specified, is basic.
|
||||
aif_realm the realm name for HTTP/HTTPS Digest auth (ignored for other types). leave unset to try whatever default realm is presented

it seems urllib in python3 doesn't support ftps, so you'll need to use ftplib if so.

server = ftplib.FTP_TLS(server, user, password)

server.login(user, password)

- use sgdisk? scripting (generated by python) for disk partitioning (part types listed at http://www.rodsbooks.com/gdisk/walkthrough.html )

-- actually, might want to use parted --script instead? then we can do percentages. https://www.gnu.org/software/parted/manual/parted.html
