Joachim Wiberg 1099d663ab conf: escape runtime strings in generated .conf files
The runparts directory and the dbus pidfile and daemon paths are
embedded in double-quoted values of the generated block files.  A
literal quote in either ends the value early and libconfuse rejects
the whole file, and a backslash is read as an escape sequence,
silently mangling the path.  The legacy one-liners had no quoting, so
neither failure existed before the block conversion.

conf_escape() doubles backslashes and escapes quotes; verified by
round-tripping hostile paths through cfg_parse_buf().
