-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.
-
-
-ip
---
-
-Newer ip commands (from iproute2) do not accept the abbreviated syntax "ip r a
-..." etc.  "ip route add ..." must be used instead.
-
-
-sed
----
-
-\s is not supported in regexps on Debian etch (sed 4.1.2), Ubuntu 4.10.  We
-hand-craft character classes instead.
