auto-import changelog data from nfs-utils-0.3.1-5.src.rpm Fri Mar 30 2001 Preston Brown <pbrown@redhat.com> - don't use rquotad from here now; quota package contains a version that works with 2.4 (#33738) Mon Mar 12 2001 Bob Matthews <bmatthews@redhat.com> - Statd logs at LOG_DAEMON rather than LOG_LOCAL5 - s/nfs/\$0/ where appropriate in init scripts Tue Mar 06 2001 Jeff Johnson <jbj@redhat.com> - Move to nfs-utils-0.3.1 Wed Feb 14 2001 Bob Matthews <bmatthews@redhat.com> - #include <time.h> patch Mon Feb 12 2001 Bob Matthews <bmatthews@redhat.com> - Really enable netgroups Mon Feb 05 2001 Bernhard Rosenkraenzer <bero@redhat.com> - i18nize initscripts Fri Jan 19 2001 Bob Matthews <bmatthews@redhat.com> - Increased {s,r}blen in rpcmisc.c:makesock to accommodate eepro100 Tue Jan 16 2001 Bob Matthews <bmatthews@redhat.com> - Hackish fix in build section to enable netgroups Wed Jan 03 2001 Bob Matthews <bmatthews@redhat.com> - Fix incorrect file specifications in statd manpage. - Require gawk 'cause it's used in nfslock init script. Wed Dec 13 2000 Bob Matthews <bmatthews@redhat.com> - Require sed because it's used in nfs init script Tue Dec 12 2000 Bob Matthews <bmatthews@redhat.com> - Don't do a chroot(2) after dropping privs, in statd. Mon Dec 11 2000 Bob Matthews <bmatthews@redhat.com> - NFSv3 if kernel >= 2.2.18, detected in init script Thu Nov 23 2000 Florian La Roche <Florian.LaRoche@redhat.de> - update to 0.2.1 Tue Nov 14 2000 Bill Nottingham <notting@redhat.com> - don't start lockd on 2.4 kernels; it's unnecessary
