triggers and lenny-to-squeeze upgrades

[Bill Allombert <Bill.Allombert@math.u-bordeaux1.fr>]

Dear developers,

There is an increased usage of triggers in squeeze and I would like to issue a
word of warning concerning lenny to squeeze upgrade:

Before removing the maintainer script code that that is replaced by the
activation of a trigger, you have to make sure that a suitable version
of the triggered package is installed, at the very least, one that register
a trigger.

To allow for lenny to squeeze upgrade (including partial upgrade), 
this means that either

1) the lenny version of the triggered package already register the trigger.
or
2) the triggering package depends on an appropriate version of the triggered
package.

otherwise there is no garanty that the trigger will be available when the
package is upgraded. This might be critical with e.g. boot loaders.

Cheers,

Imagine a large red swirl here.
