excluding multipath devices using a pre script during kickstart

[Nik Lam]

Thanks Thomas - that looks promising.

Do you ever use this LVM-based filtering with a kickstart installation?

I'm unsure of what point the lvm.conf file would be read during the
installation process. I might try some experiments, but I'm not too
hopeful.

I've noticed there is a multipath option in kickstart, which includes a
--rule= parameter, but I can't find any documentation of how it's used.

Regards,

Nik
