-# Note:
-#
-# 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.
