[ILUG] bloody redhat network init scripts (and regex's)

[Paul Jakma]

grrrr.....

the RH network init script starts up interfaces in alphabetical order.
argg... this a problem if you have tunnel interfaces that have a
dependency on other interfaces and the name of the tunnel device
happens to come alphabetically before the name of the device it is
dependent on. eg, cipcb? and eth?.

basically the order is determined by:

ls ifcfg* | egrep -v '(ifcfg-lo|:|rpmsave|rpmorig|rpmnew)' |  egrep -v
'(~|\.bak)$' | egrep -v 'ifcfg-ippp[0-9]+$' |  egrep
'ifcfg-[a-z0-9]+$' | sed 's/^ifcfg-//g'

(with /etc/sysconfig/network-scripts as PWD).

so how can i modify the sed so that it spits out any eth? interfaces
before any remaining interfaces? (or any other suggestion as to how to
quickly get this to spit out eth? before other interfaces).

clean solution is maybe for RH to add an "INTERFACES" field to
/etc/sysconfig/network, and use that if it is present. (hmm....)

Also, while i'm at it: /etc/sysconfig/static-routes doesn't support
reject routes or anything but gateway / device routes. think they'd do
the simple thing and make that file just contain lines that are punted
straight on to the route command? no.. that'd be far too fnerkin
obvious!!! instead they have another lairy hairy fscking script
(ifup-routes) to parse the static-routes file.

Sorry, correction, did i say parse? no, it's RH, so they only parse
one or two bits of it and if it matches what they expect they assume
all the rest is fine. (rather than doing a good job of parsing it ->
sanity check everything, and cover as many of the ways of adding
routes as are documented in the bloody man page).

they couldn't do the simple short way (assume admin knows best)... and
they only made a half^Wquarter-arsed attempt at the doing it the long
way.

typical RH... excellent.
