NAME
flashfs – journalling file system for flash memory

SYNOPSIS
aux/flashfs [ –Dr ] [ –n nsect ] [ –z sectsize ] [ –f file ] [ –m mountpoint ]

DESCRIPTION
Flashfs interprets the journal–based file system created by mkflashfs(8) and stored in file (default /dev/flash/fs) so that it can be mounted into a Plan 9 file system. 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.

The –s option causes flashfs to post its channel on #s/flashfs. Flashfs mounts itself on mountpoint (default /n/brzr). The –D option turns on 9P debugging output. The –r option makes the file system read–only.

The files and directory structure are divided into sectsize (default 4096) byte blocks. Larger blocks make large files more compact but take longer to access. Supplying the –n option forces file to contain exactly nsect sectors.
