I have re-worked upgrade-advisor to make it pluggable. Also it's now
hosted on collab-maint[1]. This should make it easier for anyone to
submit a plug-in that detects and warns potential issues.
How it works
------------
Before upgrading, running `upgrade-advisor pre-upgrade` will :
* Report post-upgrade recommendations from a previous upgrade, like
detecting wrong update-grub path in /etc/kernel-img.conf.
* Perform various pre-upgrade test. Currently, it mainly focuses on
warning for discontinued packages.
But the long term goal is test all potential issues listed in the
Release Notes.
After upgrading, running `upgrade-advisor post-upgrade` will :
* Perform some tests to ensure that steps listed in "Preparing for
the next release" of the Release-Notes are completed.
Your Contributions
------------------
+ Testing/Feedback is welcome (It's still beta quality, so I haven't
uploaded the package yet). To use/test it, run :
sudo apt-get install git-core
git clone git://git.debian.org/git/collab-maint/upgrade-advisor.git
./upgrade-advisor/upgrade-advisor.sh pre-upgrade
Feedback for false positive and false negative is especially welcome.
+ Help list packages that "require a human intervention" [2].
I am planning to list the installed packages that "require a human
intervention" to work after upgrade. This especially include the
packages that need to be reconfigured/migrated manually.
If you know such package, please let me know (provide a short
description, like "re-configure /etc/foo.conf").
The purpose is to let the sysadmin estimate the system "downtime".
+ Contributing a plug-in.
You can contribute a plug-in, that warns users before
they upgrade their systems.
Here's a sample plugin :
check_update_grub_path() {
# This plugin applies to Etch and above only.
[ $CURRENT_OS -lt $ETCH ] && return 0
# Verbose/Debug mode.
start_function "$FUNCNAME" "Checking update-grub path
in /etc/kernel-img.conf"
# The actual test.
if grep -E "[[:blank:]=]+/sbin/update-grub"
/etc/kernel-img.conf > /dev/null 2>&1; then
alert "The path to update-grub in /etc/kernel-img.conf
is wrong."
extra "$RELNOTES/ch-upgrading.en.html#s-for_next"
fi
#Done !
end_function "$FUNCNAME"
}

I've synch'ed some of them... but more work is needed.
Finally, I'm wondering what would be the most convenient way to
distribute this tool. Any idea ?

Great idea.

Did you consider i18n ?
gettext exists as a shell program (and you can easily provide
a function that does nothing in case gettext is not installed)
Best regards,
Vincent
