MOUNT_CHFS(8)						    BSD System Manager's Manual 					     MOUNT_CHFS(8)

NAME

     mount_chfs -- mount a CHFS flash file system

SYNOPSIS

     mount_chfs

DESCRIPTION

     Mounts a flash file system from a flash(4) device.  CHFS file systems can be only mounted from flash devices.  For regular block devices like
     SSD drives or USB drives, please use a regular file system.  The file system will be created during the first mount.  CHFS stands for Chip
     File System.

EXAMPLES

	   mount_chfs /dev/flash0 /mnt

SEE ALSO

     flash(4), fstab(5), mount(8), flash(9)

HISTORY

     CHFS was originally called ChewieFS during development.  The name was changed to avoid legal issues and to have a more neutral name.

AUTHORS

     CHFS was developed at the Department of Software Engineering, University of Szeged, Hungary.

BUGS

     CHFS has a few known bugs as of 2011.  Writing the FS full can cause problems.  Truncating a file and growing it again can cause the new
     bytes not having all zeroes, but filled with the old content instead.
