Package: radvd
Version: 1:2.20-1
Severity: wishlist

Hi,

Wish: Do `adduser _radvd` on new installs.

Actual: Make it possible to increase Standards-Version.


Version 4.5.0
=============

Released January, 2020.

9.2.1
   When maintainers choose a new hardcoded or dynamically generated
   username for packages to use, they should start this username with
   an underscore.

radvd picked a username in the past, it is not picking a new
username.

There is no requirement to change the username, and it's probably a
bad idea.

The plan is to pick a new username ....

Advantage I see is that systems getting a system user
that can by the leading underscore easily identified as system user.

One disadvantage I see is upgraded systems getting user 'radvd' un-used.
And only upgraded systems get that unused system user.

Now asking debian-devel@lists.debian.org for their view on this rename.

While you are at it, please switch to sysusers (see dh_installsysusers).

Where is the corresponding change in the systemd unit?  Do you need to
store persistent data accessible by others, or could you just switch to
dynamic user allocation? (DynamicUser=true)
