Hi,To be more precise, the problem showed up here when logcheck configuration started to use the logcheck.logfiles.d files by default, i.e. when we upgraded some hosts to bookworm. Before that, since there was no files in this directory, concatenating its files contents to the LOGFILES variable was essentially a no-op.
Yet the directory itself (and the related handling of it in the script) seems to be at least as old as stretch.
