Fedora's does not, FWIW.

Well, I have already nuked the hook from my local repo -- given the above information it seemed more like waving a rubber chicken to fix a problem that probably didn't exist anyways. Resyncing the date would be much better handled by a NM dispatch script (or the distro equivlaent) in any case. > -- > Dan -- Victor Lowther RHCE# 805008539634727 LPIC-2# LPI000140019 _______________________________________________ Pm-utils mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pm-utils
