Subject: [PATCH] install.sh: POSIX-compatible 'set -o pipefail' so 'curl | sh'
 works
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The README documents the one-liner as 'curl ... install.sh | sh',
but on Debian/Ubuntu /bin/sh is dash which rejects 'set -o pipefail'
unknown option. The shebang #!/usr/bin/env bash is honored only
when the script is invoked directly — when piped via 'curl | sh'
the running shell IS dash.

Fix: split the strict-mode setup. 'set -eu' is POSIX-portable
(every shell). 'pipefail' is then enabled conditionally only on
shells that recognise it. Every curl/tar/install step in the rest
of the script checks its own exit code, so losing pipefail in dash
costs no behaviour — the installer still fails fast on any error.
