Bug 593096

Flavio,
does command_names or prefix affect orher invocations of lvm.static that are made from mkinitrd? I can see that they change the output of vgdisplay and lvs which are used in mkinitrd but I'm not sure if parsing will go wrong in all cases.

Hi Alexander,

Yes, it does.

With the Beta 1.0 tree the duplicate bug is not happening anymore. Systems can boot fine.

Rebuild the initrd.img:
# mkinitrd -f /boot/initrd-2.6.18-300.el5.img $(uname -

lvm.conf from the newly generated initrd.img contains:

  	syslog=1
  	overwrite=0
  	level=0
  	indent=1
  	command_names=1
  	prefix="---"
