PARTFS 8
NAME
partfs - serve file, with partitions
SYNOPSIS
disk/partfs [
-Dr ] [
-d diskname ] [
-m mtpt ] [
-p 9load-parts ] [
-s srvname ]
diskimage DESCRIPTION
Partfs presents the file
diskimage in the manner of
sd (3) on
mtpt / diskname (default
/dev/sdXX ). Changes made to the disk are written through to
diskimage unless the
-r option is given.
When setting disk geometry with the geometry control message, the arguments are sectors and sector size.
The -m option causes partfs to mount its synthetic file system at mtpt instead of /dev .
The -p option causes partfs to treat 9load-parts as a partition environment variable constructed by 9load (see 9boot (8)) and adds the defined partitions. This is used primarily by boot (8) to assist booting from USB disks.
The -s option causes partfs to post its 9P service at /srv/ service .
