Comment (by needle8420):

 but ...

 #26913 does NOT fix the case of
 KeyDirectory == DataDirectory
 and
 DataDirectoryGroupReadable == 1
 and
 KeyDirectoryGroupReadable == 0 [default]

 cos in that case,
 DataDirectory is set to filemode 0750,
 but then back to 0700

 so KeyDirectoryGroupReadable
 should be made an autobool too

 this is a very rare case,
 cos by default
 KeyDirectory = ${DataDirectory}/keys
