reboot -r on mips

[Mori Hiroki]

Hi

I found new method at upgrade. That is use pipe.

This is upgrade script. This method only use 6MByte md
any size flash.

#!/bin/sh

ZBOARD=`uname -i`

. /etc/upgrade.conf

cd /tmp
mkdir bin
mkdir sbin
mkdir libexec
mkdir dev
mkdir lib
mkdir etc
mkdir -p usr/bin
cp /sbin/init sbin/
cp /bin/sh bin/
cp /bin/dd bin/
cp /bin/kill bin/
cp /libexec/ld-elf.so.1 libexec/
cp /etc/login.conf.db etc/
cp /usr/bin/tftp usr/bin/
cp /lib/libedit.so.7 lib/
cp /lib/libncursesw.so.8 lib/
cp /lib/libc.so.7 lib/
mkfifo flashpipe

kenv vfs.root.mountfrom="ufs:md0"

#echo ${ZBOARD}.zimage

echo "#!/bin/sh" > etc/rc
echo "dd if=/flashpipe of=${UPGRADEDEV} obs=${UPGRADEBS} conv=osync &" >> etc/rc
echo "echo ¥"bin
get ${ZBOARD}.zimage /flashpipe
quit¥" | tftp ${UPGRADETFTP} 69" >> etc/rc
echo "kill -INT 1" >> etc/rc
chmod a+x etc/rc

reboot -r
