# Create a users home directory and copy system profiles in place if

# This script must be referenced in /etc/auto_master in order to have
# any effect. For example:
#
#        /home /etc/auto_homedir.sh
#
# Furthermore, it must have the sticky bit set:
#
#        chmod +t+x /etc/auto_homedir.sh

# Prereq:
#        Solaris 10 requires patches 147774-01 (sparc) 147775-01 (x86)

# Input:

# Output:
#        Returns the path of the physical home dir on sdtout, ie:
