root-lvm
Hi, I've found an issue regarding root-lvm, at boot, lvm writes some files in /etc/lvmconf, /etc/lvmtab, /etc/lvmtab.d at boot in initrd and if lvm dont find enough space in ramdisk, it will not be able start up and never get root filesystem mounted... So you need to make a bigger ramdisk for initrd
It's a small summary of the problem case it's 4:00 am in the morning....
