-1- version

I am unsure about which version of LVM is included in Slackware 10(-stable).
According to the HOWTO, LVM1 is for 2.4 kernels, and LVM2 is for 2.6 kernels and especially patched 2.4 ones. This would mean that Slackware comes with LVM1 as the kernel in Slackware is not patched, and I use kernel 2.4.
OTOH, the HOWTO says it only describes LVM2 and talks about lvm_1.0.8_tar.gz. According to my /var/log/packages/, I have lvm-1.0.8-i486-1, which would mean that it's LVM2.
Finally, in my kernel .config file, it says CONFIG_BLK_DEV_LVM=y.
Can anybody tell me for sure that it's LVM2?

-2- install Slack on an VG

If I setup VG and LV on a new system after (C)FDISK and before running setup, will I be able to install Slackware using LVs with the standard installer?

Hi!

I just switched from kernel-2.4.29 to 2.6.11 and found LVM no longer working. It seems LVM-1.0.8 isn't any longer supported by 2.6.x

I simply removed the package lvm (1.0.8) and installed the packages lvm2 and device-mapper from CD2 /testing/packages/lvm2.
For now lvm is working again.
