Supported distributions
TODO: Debian, Ubuntu, Others, WSL
Configuration
Many aspect of the programs can be configured by a configuration file. A sample is provided.
cp /usr/share/doc/ucaresystem/ucaresystem.conf.sample /etc/ucaresystem.conf
sudo $EDITOR etc/ucaresystem.conf
Timeshift backups
With timeshift a snapshoot of the OS can be created before maintain and cleanup actions.
The default setting is ENABLE_TIMESHIFT=auto which enables timeshift if timeshift is installed
and operates in btrfs mode. We recommend to install and enable timeshift.
To enable timeshift in rsync mode set the option ENABLE_TIMESHIFT=yes
Reboots
Can configure automatic reboots (more...)
During sensitive operation ucaresystem will try to prevent you from rebooting. The reboot lock will hide the reboot and shutdown action from your graphical environment. This is not perfect and you can override this.
To restore the reboot functionality in case of an error remove the file
'/etc/polkit-1/localauthority/90-mandatory.d/99-ucaresystem-temporary.pkla'.
A systemd service is provided to delete this file on reboot, but systemd is not a hard dependency.
Topgrade integration
Cleanup kernels
When you do an apt autoremove kernels and headers will be cleaned except
- the currently booted version
- the kernel version we've been called for
- the latest kernel version (as determined by debian version number)
- the second-latest kernel version
This is controlled by the file /etc/kernel/postinst.d/apt-auto-removal.
Thus the clean actions will do the same.
If you need better control the tool remove-old-kernels is provided.
This is based the old purge-old-kernels from byopu, extended to remove headers also.
