>Description:
After upgrading to 9.0 from 8.1_STABLE my daily insecurity output is
claiming some files are missing:

Checking special files and directories.

./etc/auto_master missing
./etc/autofs/include_ldap missing
./etc/autofs/include_nis missing
./etc/autofs/special_hosts missing
./etc/autofs/special_media missing
./etc/autofs/special_noauto missing
./etc/autofs/special_null missing

I'm not running automount or autofs, and did the upgrade after
downloading src/ & xsrc/ from cvs and building my own 9.0 release.

postinstall doesn't seem to complain whether the files are there or
not, so it seems to me there is some disconnect between postinstall,
/etc/daily /etc/security, and build.sh install=/

Thanks

>How-To-Repeat:
upgrade from 8.1 to 9.0
>Fix:
Copying the missing files manually stopped the daily insecurity error messages, but it seems like some install script issue
