Possible /dev/null corruption by log rotate

If a log file points to /dev/null, this device will sooner or later become corrupted by cups.

The change of file permissions and ownership is prevented in
log.c - check_log_file() for all "/dev/..." logfiles.
The log rotation is not disabled.

As the file size is held internally "/dev/null" will be renamed to
"/dev/null.O" and a new ordinary file "/dev/null" will be created, when the assumed file size reaches MaxLogSize.

I suggest to add the "/dev/ - check" to the log rotation conditions.

This also regards the 1.2 versions.

Fixed in Subversion repository.

Note that you can also use the directive with no value to disable the corresponding log, e.g.:

AccessLog

disables the access log stuff.
