Subject: frontend: Require strings instead of identifiers.
X-Git-Tag: sysdb-0.1.0~163
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a5bd3248d00810f3e576de71aa5ac2ebfb2f001a;p=sysdb.git

frontend: Require strings instead of identifiers.

… for host names and name matchers. Identifiers were used as an early
work-around but they are not valid in those places.
