I can't get it to work.

; ramfs
; dd -if /dev/zero -of /tmp/cache -bs 1m -count 32
32+0 records in
32+0 records out
; {cfs -s -dS -f /tmp/cache </srv/office &} | echo 0 >/srv/office.c
; dinit: bsize 0x0<= 0
formatting disk
formatting inodes

; mount /srv/office.c /mnt/office.c
<-client: Tversion tag 65535 msize 8216 version '9P2000'
->server: Tversion tag 65535 msize 8216 version '9P2000'
cfs: sendmsg
mount: sys: write on closed pipe pc=0x2008c6

directly use -F also does not work for me.

; dd -if /dev/zero -of /tmp/cache -bs 1m -count 32
32+0 records in
32+0 records out
; cfs -F /srv/office -dknS -f /tmp/cache /mnt/office.c
dinit: bsize 0x0<= 0
formatting disk
formatting inodes
<-client: Tversion tag 65535 msize 8216 version '9P2000'
->server: Tversion tag 65535 msize 8216 version '9P2000'
cfs: sendmsg

it seems to stuck there.

putting the line in plan9.ini seems to work for tls boot.
