Bug 156009 – genkernel should check that /etc/lvm/lvm.conf is valid before merging it to initrd

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Petteri Räty (RETIRED) 2006-11-23 02:10:45 UTC]

I recently stumbled onto a problem where I had typoed my lvm.conf in the chroot. When booting the machine I found out that genkernel happily used my typoed lvm.conf in the initrd. You can use lvm dumpconfig to detect if lvm.conf is valid.

rj ~ # lvm dumpconfig
  Parse error at line 79: expected a value
  Failed to load config file /etc/lvm/lvm.conf
rj ~ # echo $?

rj ~ # lvm dumpconfig

Ehh... ok... got a patch?

[Comment 2 Chris Gianelloni (RETIRED) 2007-03-14 01:30:04 UTC]

OK, I think I've fixed this in subversion/3.4.7_pre5

[Comment 3 Chris Gianelloni (RETIRED) 2007-04-05 15:00:59 UTC]

This is fixed in genkernel 3.4.7 which is now in the tree.
