- .SH DESCRIPTION
- .I Flashfs
- interprets the journal-based file system created by
- .IR mkflashfs (8)
- and stored in
- .I file
- (default
- .BR /dev/flash/fs )
- so that it can be mounted into a Plan 9 file system.
- .I Flashfs
- is typically used to create a stand alone file system from
- a small persistent storage device, such as an erasable flash memory.
- It does not authenticate its clients and assumes each group
- has a single member with the same name.
- .PP
- The
- .B -s
- option causes
- .I flashfs
- to post its channel on
- .BR #s/flashfs .
- .I Flashfs
- mounts itself on
- .IR mountpoint
- (default
- .BR /n/brzr ).
- The
- .B -D
- option turns on 9P debugging output.
- The
- .B -r
- option makes the file system read-only.
- .PP
- The files and directory structure are divided into
- .I sectsize
- (default
- .BR 4096 )
- byte blocks.
- Larger blocks make large files more compact but take longer to access.
- Supplying the
- .B -n
- option forces
- .I file
- to contain exactly
- .I nsect
- sectors.
