[Slackbuilds-users] Build Environment Reminder

[Yiannis]

Just to be clear, this is not the same as installing the testing glibc.

Nothing on the system changes. System glibc stays 2.33. No upgradepkg of a
core package, no ld.so.conf, no ldconfig.

What the script does:

- unpacks the snap into /opt/Signal/signal-desktop
- unpacks aaa_glibc-solibs-2.42 into the same prefix, as a build source
like any tarball
- patchelf on the Electron binary so its PT_INTERP and DT_RPATH point there

So those .so files are reachable by exactly one binary. Nothing else on the
machine can see them, and removepkg takes them all with it.

Checked: /proc/PID/maps across all 7 Signal processes shows only the
bundled libc, never the host 2.33. QR link, full history sync, send and
receive all work. sbopkglint passes.

Attached if anyone wants to look.

IF admins and the maintainer agree with that then a desktop entry and an
icon needed, now run only from the terminal.

Thank you.
