filesystem is read only

[raveit65]

I installed fc17 x86_64 rc2 netiso with a kickstart file for enabling btrfs.
-- minimal
-- without bootloader (because grub2 makes to much crazy entries on a multiboot system)
Installation works fine with btrfs but if sign in in runlevel 3 i can't do nothing because the filesystem is mounted read only!
Changing the 'ro' parameter to 'rw' in the line beginning with 'linux' in the boot entry of grub2.cfg helps.
menuentry 'Fedora 17 (3.3.0-8.fc17.x86_64)' --class fedora --class gnu-linux --class gnu --class os {
load_video
set gfxpayload=1600x1200x32
insmod gzio
insmod part_gpt
insmod ext2
set root='(hd1,gpt2)'
search --no-floppy --fs-uuid --set=root 9ccdbda8-383b-4d11-8a19-280eab204357
echo 'WELCOME TO THE PLEASUREDOME...'
echo 'Loading Fedora (3.3.0-8.fc17.x86_64)'
linux /vmlinuz-3.3.0-8.fc17.x86_64 root=UUID=d8cd3d87-6a36-4763-a399-5b2eab5ccdc4 rw rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=True rd.luks=0 LANG=de_DE.UTF-8 KEYTABLE=de-latin1-nodeadkeys selinux=0 nouveau.modeset=0 rd.driver.blacklist=nouveau
echo 'Loading initial ramdisk ...'
initrd /initramfs-3.3.0-8.fc17.x86_64.img
}
But is that serious? I think there was something going wrong with the installation.

Maybe here is something not correct?

I found out that this issue is a result of the 'Move all to /usr' feature.
But mounting read only breaks every minimal installation if you can't create a directory as root.
Eg. addig a user with home directory is impossible.
etc........
