[Bug 201750] Re: Cannot remount loopfiles inside of vfat

[Agostino Russo]

** Description changed:

  Binary package hint: initramfs-tools
  
  Loopfiles inside of vfat cannot be remounted rw. This preventfs people
  from booting off loopinstallations in vfat. At the moment there is an
  exception in scripts/local to mount ntfs filesystems rw by default since
  those too cannot be remounted (bug #186117). It might be necessary to
  extend the treatment to all loopinstalation filesystems. Following are
  some of my experiments, not sure if there is some other way to be able
- to remount the host/loopfile.
+ to remount the host/loopfile using a Gutsy box (will replicate them on
+ Hardy soon).
  
  root at nbago~#mount -t vfat -o rw /dev/sda8 /mnt
  root at nbago~#mount -o loop,ro /mnt/root.disk /media/tmp 
  root at nbago~#mount -o remount,rw /media/tmp
  mount: block device /mnt/root.disk is write-protected, mounting read-only
  root at nbago~#umount /media/tmp
  root at nbago~#mount -o loop,rw /mnt/root.disk /media/tmp
  root at nbago~#mount -o remount,ro /media/tmp           
  root at nbago~#mount -o remount,rw /media/tmp
  root at nbago~#mount -o remount,ro /mnt      
  mount: /mnt is busy
  root at nbago~#mount -o remount,ro /media/tmp
  root at nbago~#mount -o remount,ro /mnt      
  mount: /mnt is busy
  root at nbago~#umount /media/tmp
  root at nbago~#umount -d /mnt
  root at nbago~#mount -t vfat -o ro /dev/sda8 /mnt
  root at nbago~#mount -o loop,rw /mnt/root.disk /media/tmp
  root at nbago~#mount -o remount,rw /media/tmp
  mount: block device /mnt/root.disk is write-protected, mounting read-only
  root at nbago~#umount /media/tmp 
  root at nbago~#losetup /dev/loop3 /mnt/root.disk 
  root at nbago~#mount -o ro -t ext3 /dev/loop3 /media/tmp
  root at nbago~#mount -o remount,rw /media/tmp           
  mount: block device /dev/loop3 is write-protected, mounting read-only
