In old Debian 10, after the release of Debian 11, apt update is failing
like this if we don't add the option "--allow-releaseinfo-change":

root@debian:~# apt update
Get:1 http://security.debian.org/debian-security buster/updates InRelease [65.4 kB]
Get:2 http://http.us.debian.org/debian buster InRelease [122 kB]
E: Repository 'http://security.debian.org/debian-security buster/updates InRelease' changed its 'Suite' value from 'stable' to 'oldstable'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

On slower hosts it takes a bit more time to boot the ISO some times, which
results with not receiving the ESC key to disable the graphic screen, and so
not working installation.

The general idea is to provide a machine connected to re6st, registered as
computer in SlapOS Master and with thorwable user to work on it.

Starting from default installation some uneeded packages are removed, and
few expected ones are added in order to have common set of packages and use
scenarios across all installations.

It's not possible on Ubuntu/Focal

The goal is to use the newest re6st-node package that correctly enables
the re6stnet service. re6st-node package has been fixed with
nexedi/re6stnet@5bdb32e6
and 6972e11f

Packer can be run on slow machines, give them time to do the job.

Only shacache assures stable URLs for reproducible builds.

This is a fixup of 5e69756c

fixup of nexedi/slapos.package@f04d923d

This reverts commit 6e5b4d76 and commit 055ffef4.

After nexedi/slapos.buildout@0abf873d we don't have compiled wheels anymore

With previous version of setuptools (33.1.1), we have errors when downloading the latest version:

While:

Having base playbook for Rapid.Space VPS servers is a good way to automate
common tasks on such servers.

Additional role rapid-space-vps-base is added for furhter extensions.

Unfortunately a lot of various approaches is needed:

 * ini_file for oneline manipulation
 * blockinfile for adding a section
 * lineinfile for uncommenting

Note: it was discovered, that some specific parts are just missing in
vifib-server, so add them there.

patsubst adds whitespaces preventing the correct file, perl
and chrpath to be used. For archlinux package file command fails
because of this.
