[Devil-linux-develop] Issues with remote update of DL

[Tim T. <t....@co...>]

While making some fixes to mount_cdrom for live update (due to issues 
with read-only mounts of disk device) it occured to me there was another 
issue - after reboot to a new version, pre_init will invoke for the 
upgrade-config script where the user will be required to provide input 
on the console. If the user is in fact at a remote location, the box is 
now hung.

Q: It looks like upgrade-config needs some post-processing to actually 
upgrade the real config?

A few alternatives occurred to me -

- Make the choice to run upgrade-config default to "no", and let user 
ssh in later to run it.  Can we setup all interactive logins to check 
for mismatch and prompt/run the upgrade script there? In some situation, 
the boot might not be succesfull unless the config is upgraded.

- Add another boot-line option like "DL_remote" that would indicate 
never to require console input. This could be used to skip the upgrade 
prompt entirely, or just change the default answer.

- Add and option to upgrade-config that takes default choices if no 
answer in n seconds, and leave the pre_init stuff alone. pre_init  could 
detect the new "DL_remote" flag and call upgrade-config with the right 
options.  The user could ssh in to accept and save the new config, or 
reject it and run the upgrade script again.

Comments?
