The sysutils/bastille port uses @sample in pkg-plist to designate its default configuration file.  However, it lists the "target_file" name, not the "sample_file" name.  This causes any local modifications to /usr/local/etc/bastille/bastille.conf to be overwritten when the package is updated.

A suggested fix is to change the config file pkg-plist entry to the following:

@sample %%ETCDIR%%/bastille.conf.sample

and to rename the distribution file in the port "bastille.conf.sample".


Note, in Example 8.3 "Real Life Example, How @sample is Implemented" in the FreeBSD Porter's Handbook (https://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/plist-keywords.html#plist-keywords-sample-example) it's clear that if only one filename is present in a @sample line then the real target file is assumed to be that filename minus the ".sample" suffix: ''target_file="${sample_file%.sample}"''  This is also stated in Section 8.6.9 ("@sample file [file]"), though the language wording is not 100% clear.

Section 8.3 ("Configuration Files") is clear in recommending the single-filename variant of @sample, using ".sample" as the suffix.  The Bastille port should be changed to adhere with this recommendation.
