mount_chfs -- mount a CHFS flash file system
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-
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.
mount_chfs /dev/flash0 /mnt

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