[Voyage-linux] persistence of changes in root filesystem

[jegunn]

Hi, Punky.

1. Always 'reboot' as root or 'sudo reboot' as mpd, never the button
 	I could understand perfectly if I used the button.
2. I wrote menu.lst; it says

title voyage-linux-02May11
root (hd0,0)
kernel /vmlinuz root=/dev/hda1 screen=800x480 video=uvesafb:800x480x16 at 60
initrd /initrd.img

3. ext2.

BUT, I just noticed that `mount' says

root at innana:~# mount
rootfs on / type rootfs (rw)
........
/dev/hda1 on / type ext2 (rw,noatime,errors=continue)
........

This cannot be good....
