Before running the chroot command, you can type "mount" to see if the
root@ttyp1[knoppix]# mount
/dev/root on / type ext2 (rw)
/dev/scd0 on /cdrom type iso9660 (ro)
/dev/cloop on /KNOPPIX type iso9660 (ro)
/ramdisk on /ramdisk type tmpfs (rw,size=186064k)
/proc/bus/usb on /proc/bus/usb type usbdevfs (rw,devmode=0666)
automount(pid394) on /mnt/auto type autofs (rw,fd=4,pgrp=394,m
/dev/hda5 on /mnt/hda5 type ext2 (rw,nosuid,nodev)
/dev/hda3 on /mnt/hda3 type ext2 (rw)
/dev/hda2 on /mnt/hda2 type ntfs (ro,nosuid,nodev,umask=000,ui
Now, from within the chroot'd environment, just run "mount -a", and
root@ttyp1[knoppix]# chroot /mnt/hda5/
Knoppix:/# mount -a
mount: block device /dev/hda3 is write-protected, mounting read-only
mount: cannot mount block device /dev/hda3 read-only
