Hi!

I’m interested on use PuppyLinux in a cluster environment. LVM2 support in this area is very important. The modular concept model of puppy (separated packages) is extremely useful, and each user can configure his personal environment very easy.

But this modularity isn’t available for KERNEL MODULES (recompiling a custom kernel for Puppy is a nightmare). The kernel configuration is omitting several not common drivers (but very interesting). One example:

CONFIG_DM_CRYPT=m
# CONFIG_DM_SNAPSHOT is not set
# CONFIG_DM_MIRROR is not set
# CONFIG_DM_ZERO is not set
# CONFIG_DM_MULTIPATH is not set
# CONFIG_DM_DELAY is not set
# CONFIG_DM_UEVENT is not set

As you can see DM_MIRROR isn’t supported by the kernel. But hot moving a “live” (equals to a mounted) volume is one of the most interesting features of LVM.

I agree that the final space is a high priority of PuppyLinux, but my suggestion is very simple:

* Please, enable as modules all features in the kernel as you can. Publish what you like on zdrv_xxx.sfs, but leave a complete package available. With this way it’s very easy to copy needed modules to a custom zdrv_xxx.sfs.

If you can’t do this (I hope you’ll do), please, enable as modules all related to LVM. I can provide a full static lvm.static binary (no more than 1.2MB) if you like to support (optionally, of course) in PuppyLinux 4.0

Please, consider this seriously!
Regards,
One fun of Puppy.

I too would welcome this as we could use Puppy in places where another distro (slackware) is required.

Any news on LVM for Puppy v4?

Anybody dare copy the Slackware kernel to their Puppy partition?
