[Pkg-shadow-devel] Bug#784596: [passwd]

Package: passwd
Version: 1:4.2-3

Currently in my system none of the user accounts have subuids, because they 
were created before subuid support was added, but a bunch of system accounts 
do have them despite being really unlikely to ever need them.

So I think there are two changes to consider:

 - Don't create subuids for system users (the 100-999 range) unless explicitly 
requested. Or is this adduser issue?

   It is not really interfering with anything, but it is unnecessarily using 
up the subuid space and for reliability it is better to force the packages 
that need them to ask for them explicitly.

 - Create subuids for real users (the 1000-60000 range) that don't have them, 
once during upgrade.

   The users can add the subuids for them if they want, but:

    - There does not seem to be a command to just “give me the default 
subuid+subgid range”, so the user has to come up with the right magic 
incantation and
    - This will lead to some tools just working on new installations and not 
working on older installations that have been upgraded for some time, which 
may lead to confusion and the reason may not be immediately obvious.
