# The ugly script below does the following:
# 1. For pre SLVM the mddb_bootlist is transformed from the
#    format used in /etc/system to the driver config file format
#    and then :id0 is appended for device ID support.
# 2. For SLVM phase 1 only :id0 is appended to the bootlist.
#
# pre SLVM format in /etc/system
# * set md:mddb_bootlist1="sd:215:16 sd:310:15"

# On non miniroot the md.conf is updated as follows:
# if /etc/system has the mddb_bootlist, convert it to the new format.
# if md.conf has the mddb_boolist append :id0 to it.
