Subject: Check if key-store directory exists
X-Git-Tag: v9.19.22~70^2~31
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=22d1fde1a5aca5db95bf269371f89cd4db2ec5d7;p=thirdparty%2Fbind9.git

Check if key-store directory exists

Similar to key-directory, check if the key-store directory exists and
if it is an actual directory.

This commit fixes an accidental test bug in checkconf where if
the "warn key-dir" test failed, the result was ignored.
