FileES server r2360-server-linux / linux-amd64

Signed release payload: binaries, the installation kit, manifest.json and
manifest.json.sig. The website verified the manifest signature and every
payload SHA-256. The tar.gz wrapper and this README are generated by the
website publisher; they are not separately signed release artifacts.

Linux is the build without a sandbox. Requirements: OpenSSH 9.8 or newer
with UsePAM yes, Subversion, openssl. Recommended: Debian 13, Fedora.

Extract into a new directory and run as root:
  sh ./install-server.sh
  FILEES_SCHEDULER=systemd sh ./linux/install-ssh.sh   (or =cron)
Then review /etc/filees/server.json and install.conf (channel=alpha-linux).
Manual: https://manual.filees.space (chapter 3.8, Server on Linux).
Do not copy binaries over a running server; update it with filees-install.
