bpgetfile workaround

Sometimes Solaris installs get stuck on bpgetfile, particularly when
installed on subnets other than 128.200.34.

(Or more generally, making Solaris autoinstalls work off subnet)

This memo details a series of workarounds that've been used successfully.

The files to be concerned with are, for example:

Solaris-9-08-2003/auto_install/Solaris_9/Tools/Boot/usr/sbin/install.d/profind

Solaris-9-08-2003/auto_install/Solaris_9/Tools/Boot/etc/rcS

Solaris-9-08-2003/auto_install/Solaris_9/Tools/Boot/sbin/rcS

Solaris-9-08-2003/auto_install/Solaris_9/Tools/Boot/sbin/sysidfind

The two rcS files are linked (or at least identical?), but he profind
and sysidfind files are unique.

In profind, in the bootparams shell function, you'll want a line like:

set -- `/sbin/bpgetfile -retries 3 install_config 128.200.34.23`

In rcS, in the bootparams_find_and_mount_cdrom function, you'll want a
line like:

set -- `/sbin/bpgetfile -r 3 root 128.200.34.23`

...in that first one, make sure to add the "root" to it - that's the
default keyword, but if you give an IP without the keyword, it's going
to use the IP as the keyword instead of root.  :-S

...and another like so, again in rcS:

set -- `/sbin/bpgetfile -r 3 install 128.200.34.23`

In sysidfind, in the bootparams_sysid_config function, you'll want a line like:

set -- `/sbin/bpgetfile -retries 3 sysid_config 128.200.34.23`

Also, there may be a snippet of code like this in ../sbin/rcS:

      # get the server's netmask
      if [ -x /sbin/get_netmask ]; then
         netmask=`/sbin/get_netmask $SERVER_IPADDR 2>/dev/null`
         if [ -n "$netmask" ]; then
            /sbin/ifconfig -a netmask 0x${netmask}  >/dev/null 2>&1
         fi
      fi

...comment it out!  It tries to make things better, but instead make
them worse.  :)

Hopefully that's all you'll require.  :)
