autoup.sh



I noticed that there is still an un-fixed version of autup.sh floating
around, especially on #debian.

Here is a new and improved version of autoup.sh, hopefully it does the
right thing with regards to selecting an ftp program.  Apparently
there are some other issues as well, but I'm not sure about other things.

to hamm.  

You need to either have a local or remote mirror mounted, or have the
latest versions of the following packages from hamm available in the
current directory:

    ldso, libc5, libc6, timezones, locales, ncurses3.0, ncurses3.4,
    libreadline2, libreadlineg2, bash, libg++272, dpkg, dpkg-dev,

libc6 is now installed.  Now run dselect to upgrade the rest of your
system.  When that's done, reboot with "shutdown -r now" for the
utmp/wtmp wrapper functions in the upgraded libc5 to take effect.

BTW, if you aren't using it already, check out dselect's "mountable"
access method.  It's much faster than the standard "mounted" method, and
it logs everything that happens in /var/log/dpkg-mountable.  You'll want
to set "Allow overwriting repeated files?" to yes, and for extra speed
set "Enable MD5 checksumming?" to no.

If you are installing manually using dpkg, remember that all libc6 (g)
libraries conflict with all the versions of their libc5 (non-g)
counterparts prior to a certain version which placed libc5 libs in
/usr/lib/libc5-compat.  This means that they conflict with your bo
versions of libc5-linked libraries, but not the hamm versions.  For
example, if you are installing xlib6g, you should install xlib6 from
hamm first before installing xlib6g unless you have nothing that depend
on xlib6 in which case you can safelyremove it.

All development packages (-dev, -dbg, and -pic) and a number of other
incompatible packages have been removed during this upgrade procedure
due to conflicts between libc5 and libc6 versions.  A list of the
removed packages are in file $RMFILE in this directory.
You will have to re-install any of these packages you need.

Finally, remember to fix up wtmp and utmp, otherwise last and
who and sac etc wont work. here's what Miquel van Smoorenburg
<miquels@cistron.nl> had to say about this recently in debian-user
mailing list:

    > 1. You need to update ALL your packages to hamm
    > 2. Reboot if you haven't done that already
    > 3. You need to move the wtmp file and truncate the utmp file:
    >    cd /var/log
    >    mv wtmp wtmp.libc5
    >    touch wtmp
    >    cd /var/run
    >    cp /dev/null utmp
    > 4. You might want to reboot again to make sure
    > 
    > This is because the "struct utmp" and thus the utmp and wtmp
    > "databases" are different between libc5 and libc6
