dopo e cmq non vi sembra tutto strano?
Quale è il problema ?
Se ti aggiorna lilo non è che ti spiana la configurazione in /etc/lilo.conf
ho fatto giusto l'upgrade della mia sid due gg fa, ha aggiornato anche lilo
ed il sistema è rimasto perfettamente bootabile, proprio perchè non ho
toccato lilo.conf
Ti ripeto che tutti i dubbi li risolvi leggendo la documentazione standard.
Allego sotto l'inizio della man page di apt-get
APT-GET(8)
APT-GET(8)
NAME
apt-get - APT package handling utility -- command-line interface
SYNOPSIS
apt-get [ -hvs ] [ -o=config string ] [ -c=file ] [ update ]
[ upgrade ] [ dselect-upgrade ] [ install pkg... ] [ remove
pkg... ] [ source pkg... ] [ build-dep pkg... ] [ check ] [
clean ] [ autoclean ]
DESCRIPTION
apt-get is the command-line tool for handling packages, and may be
considered the user's "back-end" to other tools using the APT
library.
Unless the -h, or --help option is given one of the commands below
must be present.
update update is used to resynchronize the package index files from
their sources. The indexes of available packages are fetched from
the location(s) specified in /etc/apt/sources.list. For
example, when using a Debian archive, this command retrieves and scans
the Packages.gz files, so that information about new and
updated packages is available. An update should always be performed
before an upgrade or dist-upgrade. Please be aware that the
overall progress meter will be incorrect as the size of the package
files cannot be known in advance.
upgrade
upgrade is used to install the newest versions of all packages
currently installed on the system from the sources enumerated in
/etc/apt/sources.list. Packages currently installed with new
versions available are retrieved and upgraded; under no circum
stances are currently installed packages removed, or
packages not already installed retrieved and installed. New versions of
currently installed packages that cannot be upgraded without
changing the install status of another package will be left at
their current version. An update must be performed first so
that apt-get knows that new versions of packages are available.
dselect-upgrade
is used in conjunction with the traditional Debian
GNU/Linux packaging front-end, dselect(8). dselect-upgrade follows the
changes made by dselect(8) to the Status field of available
packages, and performs the actions necessary to realize that state
(for instance, the removal of old and the installation of new
packages).
dist-upgrade
dist-upgrade, in addition to performing the function of
upgrade, also intelligently handles changing dependencies with new ver
sions of packages; apt-get has a "smart" conflict resolution
system, and it will attempt to upgrade the most important packages
at the expense of less important ones if necessary. The
/etc/apt/sources.list file contains a list of locations from which to
retrieve desired package files.
install
install is followed by one or more packages desired for
installation. Each package is a package name, not a fully qualified
filename (for instance, in a Debian GNU/Linux system,
libc6 would be the argument provided, not em(libc6_1.9.6-2.deb)). All
packages required by the package(s) specified for installation
will also be retrieved and installed. The /etc/apt/sources.list
file is used to locate the desired packages. If a hyphen is
appended to the package name (with no intervening space), the iden
tified package will be removed if it is installed. Similarly a
plus sign can be used to designate a package to install. These
latter features may be used to override decisions made by
apt-get's conflict resolution system.
A specific version of a package can be selected for
installation by following the package name with an equals and the version
of the package to select. This will cause that version to be
located and selected for install. Alternatively a specific distri
bution can be selected by following the package name with a
slash and the version of the distribution or the Archive name (sta
ble, frozen, unstable).
Both of the version selection mechanisms can downgrade
packages and must be used with care.
If no package matches the given expression and the expression
contains one of '.', '?' or '*' then it is assumed to be a POSIX
regex and it is applied to all package names in the
database. Any matches are then installed (or removed). Note that matching
is done by substring so 'lo.*' matches 'how-lo' and 'lowest'.
If this is undesired prefix with a '^' character.
remove remove is identical to install except that packages are
removed instead of installed. If a plus sign is appended to the package
name (with no intervening space), the identified package will
be installed.
source source causes apt-get to fetch source packages. APT will
examine the available packages to decide which source package to
fetch. It will then find and download into the current
directory the newest available version of that source package. Source
packages are tracked separately from binary packages via
deb-src type lines in the sources.list(5) file. This probably will
mean that you will not get the same source as the package you
have installed or as you could install. If the --compile options
is specified then the package will be compiled to a binary
.deb using dpkg-buildpackage, if --download-only is specified then
the source package will not be unpacked.
A specific source version can be retrieved by postfixing the
source name with an equals and then the version to fetch, similar
to the mechanism used for the package files. This enables
exact matching of the source package name and version, implicitly
enabling the APT::Get::Only-Source option.
Note that source packages are not tracked like binary
packages, they exist only in the current directory and are similar to
