SUSE Liberty Linux to be removed from Uyuni documentation

[keichwa]

SUSE Liberty Linux is also missing in the left navigation
=-=-=-=-=-=-=-=

AFAIK, SLL is not supported with uyuni. I'm not sure how this file slipped in (is it linked from somewhere else?).

this worries me: https://suse.slack.com/archives/C02D12QAXV1/p1703084354752169?thread_ts=1703081649.600679&cid=C02D12QAXV1

This example

ifeval::[{suma-content} == true]
**** xref:clients-sleses.adoc[SUSE Liberty Linux Clients]
endif::[]

appears in the Uyuni antora output (and in the search index). It (correctly) does not appear in the left navigation bar. Maybe, the new antora needs different keywords or config switches. This section does not appear in the PDF.
