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 mk‐
flashfs(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.
