concurrent usage of zfs with different kernels

Is there a good way of installing the necessary zfs/spl modules for multiple kernels?  Say, the mainline kernel and the lts kernel?  Every combination I try (from the archzfs repo or from the AUR) seems to list the other as a conflict.  I didn't have a lot of luck with the AUR zfs-dkms package before.

Re: concurrent usage of zfs with different kernels

At least mainline and -lts kernels can be installed together from aur  withouth any problem:

Re: concurrent usage of zfs with different kernels

Strictly speaking the arch linux package in the repositories tracks linux stable not linux mainline in general.

The headers conflict though.

What requires the headers?

They shouldn't. Specifically?

Re: concurrent usage of zfs with different kernels

Still not seeing an ACTUAL conflict. Looks like a case of really bad packaging. That PKGBUILD is ... marginal.

Re: concurrent usage of zfs with different kernels

So the package zfs-linux-headers conflicts with zfs-linux-lts-headers but you are saying there is no reason for that conflict entry if I understand you correctly?

Re: concurrent usage of zfs with different kernels

It appears to be using the full kernel release version in the path, so no, it should not have that conflict entry. If there is something that does conflict, it should be split out.

These PKGBUILDs (spl-linux{-lts},zfs-linux{-lts} are little tricky: they are created with intention to build in clean chroot and push  to custom repository for later use. On live system (spl|zfs)-linux{-*}-headers can be safe removed after  corresponding  (spl|zfs)-linux{-*) package instalation. (* = lts,zen,hardened...)

Which is just crappy packaging.

As Scimmia said...

It is not any harder to create a decent PKGBUILD for use in the AUR than it is to create a PKGBUILD for use in some arbitrary custom repo tooling which relies on a clean chroot.

If a PKGBUILD is that gross, and its author only intends it for building some custom repository, then in the general nature of things I question whether that maintainer is responsible enough to be maintaining AUR packages.

Well, all of this is somewhat worrying.

Is there a better way of using ZFS on Arch?
