DIY DICE roaming

A normal DIY DICE machine (including one running as a VMware guest) will only function when connected to the DICE network; this is because it relies on the DICE infrastructure, eg. for account details and passwords. For a DIY DICE machine to "roam" it must be configured to use local user accounts and home directories; you can use the ADD_LOCAL_ACCOUNT macro to do this for you.

• install as per instructions for non roaming machine
• modify LCFG profile
• make sure profile received
• reboot and check still working
• powerdown and convert VMware guest to using NAT rather than bridged network
• reboot and check still working

• updaterpms no longer runs at boot - need to run manually --- "/usr/bin/lcfg-update"
• cron jobs ---- "/usr/bin/lcfg-update"
• profile changes will take longer as won't receive notifies from LCFG server
• need to use fully qualified DNS for inf hosts
• probably want to set root passwd so can debug problems when roaming.
• use ADD_LOCAL_ACCOUNT(account,passwd entry) to add an account
• use ADD_LOCAL_USER(account, passwd entry) to add an account, allow it to login and create a homedirectory
• use "openssl passwd -1" to create an encryted passwd from a plaintext passwd.
