Alot of the mount options just don't get processed on remount. I
complained about this back when noatime got into the 2.0.x source.

I recently ran into the same problem with Solar Designer's secure-linux
patches. I wanted to remount /proc with gid=55 so group proc could see
most of proc. mount -o remount,gid=55 /proc did not do I ended up
rebooting after editing /etc/fstab.

Are you sure you stopped _all_ programs that were using the network? I've
seen gated do amazingly bad things when I yank the tulip driver out from
under it. Everything from oopses to eating all virtual memory. I wrote
it off as pilot error rather than kernel bugs.
