Command Incompatibilities ========================= Known incompatibilities with various commands on various distributions, and the workarounds we use. brctl ----- brctl show 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.
