MOUNT_CHFS(8)           NetBSD 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 Sys-
     tem.

     This command is normally executed by mount(8) at boot time.

     The options are as follows:

     -o      Options are specified with a -o flag followed by a comma-sepa-
             rated string of options.  See the mount(8) man page for possible
             options and their meanings.


EXAMPLES

           mount_chfs /dev/flash0 /mnt


SEE ALSO

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


HISTORY

     A mount_chfs utility appeared in NetBSD 6.0.  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.
