Which operating systems are supported (Fedora, RHEL, Debian)?

Officially and practically supported:

• Fedora (primary development platform);
• RHEL / Rocky / AlmaLinux (production-oriented systems);
• Debian / Debian-based distributions (including Ubuntu — without distribution-specific dependencies).

Requirements:

• systemd;
• a modern Linux kernel;
• standard user-space tools (glibc, iproute2, etc.).

Exotic distributions may work, but are not tested and not supported.
