Sommaire

NAME

debdelta-upgrade - Downloads all deltas that may be used to 'apt-get upgrade', and apply them.

SYNOPSIS

debdelta-upgrade

DESCRIPTION

This program is designed to download changes (deltas) that may be used to apt-get upgrade , and apply them. See debdelta(1) for more details on the delta files.

OPTIONS

--dir DIR directory where to save results.

     (default: /var/cache/apt/archives for root, 
     /tmp/archive for non-root users)
--deb-policy POLICY policy to decide which debs to download,

  it is a comma separated list of (abbreviations of)
    source =  there is no /etc/debdelta/sources.conf line
    big =  the delta is too big
    error =  the delta fails to apply
    unavailable = all other cases
    after = continue downloading debs after patching has ended
  default is s,b,e
-v verbose (can be added multiple times).
-d add extra debugging checks.
-k keep temporary files (use for debugging).

EXAMPLES

When invoked as root, apt-get update && debdelta-upgrade && apt-get upgrade will download delta files, recreate the needed Debian packages, and then upgrade your Debian host. When only slow Internet connection is available, the above procedure may be significantly faster than "apt-get update && apt-get upgrade". (Use -v to see how much faster.)

SECURITY

A Debian package that is recreated using debbdelta-upgrade is byte-by-byte identical to the original one; when "apt-get upgrade" is subsequently invoked, the cryptographic archive authentication support (see apt-secure(8) ) will guarantee that it can be trusted to be installed. Currently, though, the delta file itself is not cryptograhically protected.
