I was simulating a fresh install using VM Ware session and the latest gentoo boot iso. When setting up LVM stuff I had problems that where /etc/lvmtab.d/foo wasn't being created when I ran `vgscan` (I think) because there wasn't enough free space on the file system. I solved this by removing some module files I wasn't using. I wasn't going to report this but it hit me that you could use a tmpfs mounted on /etc/lvmtab.d and it wouldn't make the ram disk for the root filesystem bigger which I can see why you'd want to keep it small.
A simple solution is to just deleate some files. For example: ./installl.txt /bin/ssh /bin/scp /usr/sbin/xfs_repair /usr/sbin/raidtools This should reduce capacity to 94% or so. Becarefull when making changes as /etc/lvmconfig/<VolumeGroupName> gets rewritten each time a change is made so you will see /etc/lvmconfig/<VolumeGroupName>.old If disk capacity increases to 99% again, just remove these by rm /etc/lvmconfig/.*.old Use this untill a boocd is created with more ramdisk space.

This is fixed in the latest -r15.iso (being uploaded very soon)
