+# SLES11 SP4 runs pre-2.13 glibc, which requires vsyscall support. Most
+# distros nowadays disable vsyscall. To run this container, the host needs to
+# have vsyscall=emulate in its kernel command line.
+#
+# Due to various issues in SLES11 SP4, you might want to disable building
+# certain components. Known *not bulding* components include OVMF, SEABIOS
+# and upstream QEMU.
