[php-maint] Bug#845199: dolibarr broken after upgrading from 3.5.8+dfsg1-1 to 4.0.2+dfsg4-1 and purging php5 packages

[Ondřej Surý]

TL;DR patches or ideas accepted

Hi Raphael and Jean-Marc,

the problem in any automatic solution is in the fact there are two kind
of PHP users:

1. php got pulled as dependency and is used in default config (e.g. end
users)
2. php was installed by hand and is carefully configured (e.g. web
hostings)

Any automatic switch for group 1 would be ok, but it probably won't be
ok for group 2.

So if you have any ideas, how to handle everything automatically and not
break anything, I am all ears. Otherwise I think the Debian release
notes would be our best option right now.

Cheers,
