No, this started after I upgraded from f14 to f15. My grub entry says:

kernel /boot/vmlinuz-2.6.38.8-31.fc15.x86_64 ro
root=UUID=XXXXXXXXXXXXXXXXXX rhgb quiet SYSFONT=XXXXXXXXX
LANG=en_US.UTF-8 KEYTABLE=XX
initrd /boot/initramfs-2.6.38.8-31.fc15.x86_64.img

and It's been like this since f10 I think. I saw that when I boot from
livecd/-dvd I didn't get those messages.

However during the boot process there is a messages saying
"...remounting root fs read-write...". Should I change the grub entry
(delete the ro) and if so what'll be the impact of this? Why was "ro"
passed to the kernel in the first place, anayway?
