# NAME

`mount_puffs` —
helper utility for mounting puffs/refuse file systems

# SYNOPSIS

`mount_puffs` | [`-o` options] program[#source] mount_point

# DESCRIPTION

The `mount_puffs` utility simply executes the given program, allowing to mount puffs(4) and refuse(3) based file systems via `mount -a` or the fstab(5) file.

This command is usually only executed by mount(8), as users can directly execute file servers to mount them. The program parameter is either the path to the file server or the file name of it. In the latter case the program is searched in the `PATH` variable. The source parameter, when specified, will be passed to the program as its first non-option argument, with mount_point being the second one.

The options are as follows:

`-o`
  Options are specified with a `-o` flag followed by a comma separated string of options. They are passed to the program without any modifications except for `getargs`, which is typically used by `mount -vv`. When there is `getargs` in the list, `mount_puffs` discards all the other options and prints the kernel arguments for a puffs(4) file system already mounted at mount_point.

# EXAMPLES

Mount `dmesgfs` at /dmesg:
`# mount_puffs dmesgfs /dmesg`

Or in fstab(5):

    dmesgfs  /dmesg  puffs  rw

These are equivalent to:

`# dmesgfs /dmesg`

Mount /usr/bin/rot13fs for /home/foo at /mnt/rot13 with option `-o` `rdonly`:

`# mount_puffs -o rdonly /usr/bin/rot13fs#/home/foo /mnt/rot13`

Or in fstab(5):

    /usr/bin/rot13fs#/home/foo  /mnt/rot13  puffs  rdonly

These are equivalent to:

`# /usr/bin/rot13fs -o rdonly /home/foo /mnt/rot13`
