It doesn't solve the issue that it might be on a different unit in Dom0. To get ground that, you might like to label the filesystem as before, and refer to it in Dom0 as /dev/disk/by-label/foo Happy new year ! -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

The only remaining problem here might be that /dev/sda3 doesn't reference the same drive on each dom0 boot process... So you'd have to write a udev rule for that. Alternatively your could write a little dom0 script to do the attachment by disk ID (/dev/disk/by-uuid) rather than via --persistent. But I might also be wrong and Qubes OS solved that referencing issue internally. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
