NAME

mount_swapfs − mount swapfs filesystem (internal command)

SYNOPSIS

/usr/etc/mount_swapfs backfile frontfile swapfs opts

DESCRIPTION

mount_swapfs is a command invoked by mount(8) to mount the swapfs filesystem.  The swapfs filesystem is used for optimizing swap performance and disk usage.  mount_swapfs is not intended to be launched directly. Instead, you can invoke this command through mount(8) by using the "-t swapfs" option.  backfile is the name of the backing store which the swapfs filesystem will write into.  frontfile is the name of the mount point where the swapfs filesystem will be mounted.  The swapfs only contains one file, and it will appear at the named mount point.  swapfs is literally the characters in "swapfs".  opts are the mount options passed from mount(8).  They are ignored by mount_swapfs.

BUGS

frontfile must not exist before mounting.
