That's bad, and exactly what would/could happen with my proposal. Even if we swap the direction of the symlinks, it would still break in the other way i.e. if you tried to do the same thing under /opt/fedora-ds/slapd-instance/config - and if you tried to backup/restore with tar, you would either be getting only the symlinks, or if following symlinks, they would be broken upon restore. So, is there a way to have both? If not symlinks, then what? > > -Mark Schwenk > > -- > Fedora-directory-users mailing list > Fedora-directory-users at redhat.com > https://www.redhat.com/mailman/listinfo/fedora-directory-users -------------- next part -------------- A non-text attachment was scrubbed...
