A thorough examination of /etc/rc.subr shows that a startup script sources a certain /etc/rc.conf.d/"$_name". Maybe I should try to place "export KRB5_KTNAME=/home/svn/svn.keytab" there. At least /etc/rc.conf.d/svnserve will be sourced only once at svnserve startup, and not hundreds of times like rc.conf. But anyway, I don't like the idea of placing commands (not variables) in /etc/rc.conf* There should be support for the rc.d framework to assign limits, environment variables and login classes. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN sip:sudakov@sibptus.tomsk.ru
