# Caution!!!!
#
# LiveCD`s batch mode instalation does NOT requires user confirmation, take care.
#
# To use the batch mode, you just need to run the script with 4 inputs:
# instalar_freebsd.sh harddisk root swap var (ie:
# instalar_freebsd.sh ad0 200 256 2000, will install freebsd seting 200MB for
# the / partiton, 256MB for swap, 2GB for /var and the remaining disk free space
# to the /usr partitioin
# 
# If the script is ran without the 4 necessary user input parameters, it starts
# the Interative Mode asking for inputs one by one

# Portuguese Caution message just like the above one.
#
# Atencao!!!!
# 
# A execucao em modo batch NAO pede confirmacao, use com cuidado!!!
#
# Para usar em modo batch batch , basta executar o comando com 4 parametros:
# instalar_frebsd.sh disco raiz swap var, por ex: 
# instalar_freebsd.sh ad0 200 256 2000, instala o freebsd criando 
# - / com 200MB
# - swap com 2256MB
# - /var com 2GB
# - /usr com o restante do disco
# Se executar com menos de 4 parametros entra em modo interativo.
