+Command Incompatibilities
+=========================
+
+Known incompatibilities with various commands on various distributions, and
+the workarounds we use.
+
+
+brctl
+-----
+
+brctl show <bridge> fails on SLES9 SP2. Workaround is to use brctl show
+without arguments, and grep, though this would be difficult were you to need
+to check for a specific bridge-interface pair, since brctl does not show the
+bridge name on every line.
+
+
+ifup / ifdown
+-------------
+
+SuSE requires an extra parameter to ifup, which is created by calling getcfg
+appropriately. See xen-network-common.sh for details.
+
+Gentoo doesn't have ifup/ifdown; appropriate alternatives are defined in
+xen-network-common.sh.
