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.
