		23	`.SH DESCRIPTION`
		24	`.I Flashfs`
		25	`interprets the journal-based file system created by`
		26	`.IR mkflashfs (8)`
		27	`and stored in`
		28	`.I file`
		29	`(default`
		30	`.BR /dev/flash/fs )`
		31	`so that it can be mounted into a Plan 9 file system.`
		32	`.I Flashfs`
		33	`is typically used to create a stand alone file system from`
		34	`a small persistent storage device, such as an erasable flash memory.`
		35	`It does not authenticate its clients and assumes each group`
		36	`has a single member with the same name.`
		37	`.PP`
		38	`The`
		39	`.B -s`
		40	`option causes`
		41	`.I flashfs`
		42	`to post its channel on`
		43	`.BR #s/flashfs .`
		44	`.I Flashfs`
		45	`mounts itself on`
		46	`.IR mountpoint`
		47	`(default`
		48	`.BR /n/brzr ).`
		49	`The`
		50	`.B -D`
		51	`option turns on 9P debugging output.`
		52	`The`
		53	`.B -r`
		54	`option makes the file system read-only.`
		55	`.PP`
		56	`The files and directory structure are divided into`
		57	`.I sectsize`
		58	`(default`
		59	`.BR 4096 )`
		60	`byte blocks.`
		61	`Larger blocks make large files more compact but take longer to access.`
		62	`Supplying the`
		63	`.B -n`
		64	`option forces`
		65	`.I file`
		66	`to contain exactly`
		67	`.I nsect`
		68	`sectors.`
