[masuch]

Hi,
I have got error in chroot (precise ubuntu 64bit as host as chrooted):

Can anybody please explain me how should be properly bind /var/lock/lvm and /var/lock/dmraid in chroot (because it is going through symbolic link ... ) ?

Thank you,
Kind Regards,
M.

I just encountered the same problem.

Solution is to also bind /run before you chroot, like you did for /dev, /dev/pts and /proc:

sudo mount --bind /run  /where_you_mounted_your_chroot/run
