You can replace the binary produced by boot.c by a shell script as follows:
in your kernel config file, change the 'bootdir' section to
include all the programmes you will use in the shell script, e.g.
bootdir
/386/bin/rc
/rc/lib/rcmain
/386/bin/bind
/386/bin/sed
/386/bin/srv
/386/bin/cat
/386/bin/cp
/386/bin/rm
/386/bin/echo
/386/bin/mount
/386/bin/sleep
/386/bin/ip/ipconfig
/386/bin/auth/factotum
/386/bin/ls
/386/bin/ps
/386/bin/auth/wrkey
boot.rc boot
and in the appropriate kernel architecture subdirectory (in this
case '386') create the shell script you want to run as /boot in
boot.rc, e.g.
#!/boot/rc -m /boot/rcmain
cpuserver=yes
cd /boot
echo boot...
bind -a '#I' /net
bind -a '#l0' /net
bind -a '#S' /dev
bind '#p' /proc
bind '#d' /fd
bind -a /boot /
ipconfig -D
authaddr=`{sed -n 's/ auth=(.*)/\1/p' /net/ndb|sed 1q}
if(~ $authaddr '')
authaddr=xxx.xxx.xxx.xxx
fsaddr=`{sed -n 's/ fs=(.*)/\1/p' /net/ndb|sed 1q}
if(~ $fsaddr '')
fsaddr=xxx.xxx.xxx.xxx
factotum -sfactotum -S -a $authaddr
if(! srv tcp!$fsaddr!564 boot)
exec ./rc -m/boot/rcmain -i
if(! mount -c /srv/boot /root)
exec ./rc -m/boot/rcmain -i
bind -ac /root /
rootdir=/root
rootspec=''
/$cputype/init -c
exec ./rc -m/boot/rcmain -i
where xxx.xxx.xxx.xxx is replaced by local default ip addresses
for the auth and file servers.
