bq. This default mapping is for all bundles in the system which are not just
Sling bundles.
Would this work with subsystems, where the same bundle (i.e. same bsn) could be
deployed in different subsystems?
Regarding prefixes, I think {{serviceuser--}} would be fine. I'd also be fine
without a prefix, though.
Edit: maybe it's worthwhile to also look at the grammar for bundle symbolic
names.
{noformat}
Bundle-SymbolicName ::= symbolic-name ( ';' parameter ) *
symbolic-name ::= token ( '.' token )*
token ::= ( alphanum | '_' | '-' )+
alphanum ::= [a..zA..Z0..9]
parameter ::= directive | attribute
directive ::= extended ':=' argument
attribute ::= extended '=' argument
argument ::= extended | quoted-string
extended ::= ( alphanum | '_' | '-' | '.' )+
quoted-string ::= '"' ( ~["\#x0D#x0A#x00] | '\"' | '\\' )* '"'
{noformat}
While the quoted-string gets a bit involved, we could just split off the
optional {{(';' parameter)*}} and focus on the {{symbolic-name}} for deriving a
user-name.
So {{@}} or {{+}} to join the symbolic name and sub-service-name would
definitely avoid clashes, while {{-}}, {{_}} or {{.}} all seem problematic
(even if doubled).

> As discussed in [1] we should aim at making Sling configurationless again.
> One part which currently always needs configurations is the service user
> mapper. We should add a default mapping, from a bundle symblic name and sub
