I'm all confused. When I change my fc8 machine's fstab to
LABEL=/ / ext3 relatime 1 1
the machine won't boot - ext3 claims to not recognise the mount option.
But putting "commit=100" in there works OK, as does running `mount
-oremount,relatime' after it has booted. relatime is a vfs option, not a
fs option, but should that matter?
It'll be due to me running `/sbin/new-kernel-pkg --mkinitrd', which takes
things out of /etc/fstab and stuffs them into initrd.
I fell I'm missing something obvious here. Help?

The nash mount builtin doesn't understand the relatime mount option and
consequently can't pass the MS_RELATIME flag to mount(2).
Fedora kernels are patched to mount every filesystem with norelatime.

OIC. Thanks. That's pretty obnoxious. It'd be saner to put a copy of mount(8)
into the initrd?
