Those were required to streamline new installs with updates before 0.27.
Since 0.29 will not allow direct upgrades from <0.27 to 0.29 we might as
well remove it.
Move files for packaging outside the docs directory into its own
packaging directory. Replace the existing postinstall and postremove
scripts with Debian maintainerscripts to behave more like a typical
Debian package:
* Start and enable the headscale systemd service by default
* Does not print informational messages
* No longer stop and disable the service on updates
This package also performs migrations for all changes done in previous
package versions on upgrade:
* Set login shell to /usr/sbin/nologin
* Set home directory to /var/lib/headscale
* Migrate to system UID/GID
The package is lintian-clean with a few exceptions that are documented
as excludes and it passes puipars (both tested on Debian 12).
The following scenarious were tested on Ubuntu 22.04, Ubuntu 24.04,
Debian 11, Debian 12:
* Install
* Install same version again
* Install -> Remove -> Install
* Install -> Purge -> Install
* Purge
* Update from 0.22.0
* Update from 0.26.0
