Hi,
at home I run a server with actually to many stuff on it to be safe. But
i want to test a lot of things that it evolved to this situation. It has
ldap, samba, courier, spamassassin, clamav, squirrel, exim4,...
Anyway, for normal quick restores, restoring a backup is quick and painless.
But i was thinking of a way to not only "restore" the system but also
"move" it. For instance, my system acts weird sometimes because of my
tampering with it so i would love to start from a clean sarge install
but with all my data and services running on it without spending to much
time on the reinstall.
To manage things better i've begun moving services to uml instances on
the server and it keeps thing organised.
Now this also makes restoring the services easy as one would only have
to install a base system, install needed utils (uml,bridge) and copy the
uml files containing the systems and start those.
As for other files like /etc/profile, /etc/inputrc, /etc/environment, i
guess you could make a package containing those files and installing
them when you install the "customizing" package or whatever you would
call such a package.
A server reinstall or recovery would look like this:
* install debian
* install "mybase" package
which would be a fake pacakge depending on real apps that you want to
* install like aptitude less vim
* install "base config files" package
package containing config files, ...
/etc/profile
/etc/inputrc
/etc/skel
/etc/environment
/etc/bash.bashrc
...
This would leave you with a server "customized" to your liking and with
the base apps you can't do without. Then further customizing would be
required to run the services:
* install "uml base" package
installs uml-utilities bridge-utils + config files + root file system
/etc/init.d/uml-bridge
/etc/init.d/uml-start
/usr/local/uml/rootfs_template
/usr/local/uml/rootfs
Next would be restoring the data
* restore /root /home
As for backups, you would need to backup /root /home and the uml systems
+ maintain changes you make to files used in the custom packages.
As said, this is not the fastest restore method but with regards to
reinstalling a server it might be pretty quick and versatile.
1. Is this doable? Any things i'm overlooking/comments/...
2. What would be an easy way to making such custom packages be it for
installing config files or fake packages used to install your favourite
apps?
Regards,
Benedict
