Bugzilla Bug 171593

The rcscript addon udev-start.sh calls volume-managers to create its device
nodes for already active volumes. This is only needed for the checkroot
init-script, as / is already mounted, and after checkroot the normal addons for
volume-managers are started.

To not get more problems with volume-orders (not being configurable at that
place) we should remove that part completely, see Bug #170027.

Only remaining problem to be solved then, is: 
checkroot init-script, which calls "fsck /".
fsck then tries to access device-node for root device (getting the info from
fstab/its internal db).

Uberlord suggested to just disable fs-checking in fstab for cases where
/dev/mapper/.... (which is garanteed to exist) cannot be easily used in fstab.

i dont think i got back to you on this after we chatted about it in the base
channel ...

for baselayout-1.12.x, we'll happily move the volume crap into the checkfs
script

for 1.13.x and beyond, we'll move to proper init.d scripts

The problem is now reduced to baselayout-1.
udev-start.sh no longer executes this code for baselayout-2.

@robbat, Cardoe:
I found some code, that basically is/was the Phase I of volume-init we talked
about yesterday.

This code is from udev-start-104-r12.sh:
        # Create nodes that udev can't
        ebegin "Finalizing udev configuration"
        [ -x /sbin/dmsetup ] && /sbin/dmsetup mknodes &>/dev/null
        [ -x /sbin/lvm ] && \
                /sbin/lvm vgscan -P --mknodes --ignorelockingfailure
&>/dev/null
        # Running evms_activate on a LiveCD causes lots of headaches
        [ -z "${CDBOOT}" ] && [ -x /sbin/evms_activate ] && \
                /sbin/evms_activate -q &>/dev/null
        eend 0


It got reduced for newer udev versions to (from udev-start-115-r6.sh):

        # Only do this for baselayout-1*
        if [ ! -e /lib/librc.so ]; then

                # Create nodes that udev can't
                ebegin "Finalizing udev configuration"
                [ -x /sbin/lvm ] && \
                        /sbin/lvm vgscan -P --mknodes --ignorelockingfailure
&>/dev/null
                # Running evms_activate on a LiveCD causes lots of headaches
                [ -z "${CDBOOT}" -a -x /sbin/evms_activate ] && \
                        /sbin/evms_activate -q &>/dev/null
                eend 0
        fi

zzam: yeah, make that code run always, and we should be good for the PhaseI.
