CARP in RELENG_4

[Frank]

Hi,

I'm thinking about using the CARP patchset

http://people.freebsd.org/~mlaier/CARP/20040823-carp.RELENG_5.diff

and porting it back to RELENG_4.

Before I start doing that, I want to check first, if this is an accomplishable goal. So, my question is, does anybody know a reason (eg. major incompatibility beteen FreeBSD 4.x and FreeBSD 5.x) that makes this task difficult or even impossible? Or can this be done easily enough????

Regards,

Frank
