Re: [Devil-Linux-discuss] Devil-Linux headless/remote upgrade

[Frank W. <Fra...@ct...>]

Hi, 

I have done remote updates in the past, but it is a fiddly task... 

Regarding the config part, I fetched a copy of etc.tar.gz (as it was
called at the time), and did the interactive update locally on another
machine.

I then copied the new bootcd.iso and etc.tar.gz to the remote firewall
on a second partition of the CF-Card. I'd create an entry in grub.conf
that would use the new config and bootcd.iso using the DL_xxx boot
parameters, and mark this entry as default. 

Finally I would reboot and have remote person standby to revert to the
'safe' grub entry in case anything went wrong..


These days, I prefer to create entirely new CF-Cards and send them over.
One has just to be careful
with /etc/udev/rules.d/70-persistent-net.rules when preparing the config
on a different hardware, otherwise the NICs come up with wrong names and
your locked out.

I think being able to select the iso and the config file at boot time is
the best DL can do if you want to it without touching the remote
hardware.


Regards,
Frank
