Under what circumstances are DM_DISABLE_UDEV=1 and --noudevsync safe? In Qubes OS, for example, I am considering using one or both of these, but only for operations performed by qubesd. systemd-udevd will still be running, but it will be told to create no symlinks for the devices these commands create or destroy. systemd-udevd will still be in charge of other devices, however, and other lvm2 commands may run that use neither of these. -- Sincerely, Demi Marie Obenour (she/her/hers) Invisible Things Lab
