I think the assumption that the SNMP system user and group are always
created by an old snmpd package is something we can increasingly say is
There is no hard requirement to remove users and we have the situation
where this user may not even be "owned" by the package.
I see two solutions here:
a) Never remove the SNMP user and group
b) Only remove them if it's an upgrade and the previous snmpd version was
before the username change.
a is real simple but may leave some old config
b doesn't catch everything but means that the user only gets deleted during
the transition. So if the system user is used by snmpd and something
locally it still gets deleted.
I'll look into what versions of snmpd we have. I see the second option only
useful if stable has the old username.
My intention is to release a new SNMP set of packages late this weekend to
fix the security bug, so ideally I'll fix this too.
