Notifies multiple times that the machine needs rebooting

Bug #22105 reported by Crispin Flowerday on 2005-09-20
Affects Status Importance Assigned to Milestone
update-notifier (Ubuntu)

Bug Description

I know that individual packages tell the update-notifier process what to show,
but potentially now, after a system upgrade, you could be told multiple times
that you need to reboot (e.g. kernel, hal, dbus).

Wouldn't it be better to have each of those packages touching a file that
update-notifier spots, and then update-notifier gives a single stock warning
telling the user to reboot.

Thanks for your bugreport.

update-notifier can't enforce a policy here. It tries it's best to not show
duplicates (e.g. by checking for identical notifications and skiping them).

Just to flesh my idea out:

When a package requires a reboot for it work properly, it creates an empty file
(e.g. "/var/lib/update-notifier/require-reboot")

update-notifier spots this and then shows a 'stock' notification text, e.g:

<b>Reboot required</b>

Parts of your base system have been upgraded. You should
reboot your machine soon to ensure the upgrades are effective.

Once the message has been shown to the user (or a reboot happens),
update-notifier would remove the file.

Although (obviously) update-notifier can't enforce this policy, there could be
an ubuntu policy so that all the ubuntu packages that need reboots just have to
touch the file. I just didn't like being told that dbus needed a reboot, and
immediately hal needed one :-)

Thanks for this additional data.

I like the idea of having a pre-defined hook for this very common task. Asking
that a reboot is required seems to be the most common action for update-notifier
these days.
