It is not sensible at all and can be considered dangerous. Neither is the behaviour conventional (as `auto` in fstab should only affect behaviour on boot and `mount -a`) or ever documented at all (not even in systemd, see systemd.mount(5) and crypttab(5)). + +(cherry picked from commit 142b8142d7bb84f07ac33fc00527a4d48ac8ef9f) +--- + src/core/mount.c | 6 +----- + src/cryptsetup/cryptsetup-generator.c | 4 ---- + 2 files changed, 1 insertion(+), 9 deletions(-) + +diff --git a/src/core/mount.c b/src/core/mount.c +index c31cad6..7064fa1 100644 +--- a/src/core/mount.c ++++ b/src/core/mount.c +@@ -338,7 +338,6 @@ static int mount_add_mount_dependencies(Mount *m) { + } + + static int mount_add_device_dependencies(Mount *m) { +- bool device_wants_mount; + UnitDependencyMask mask; + MountParameters *p; + UnitDependency dep; +@@ -368,9 +367,6 @@ static int mount_add_device_dependencies(Mount *m) { + if (path_equal(m->where, "/")) + return 0; + +- device_wants_mount = +- mount_is_auto(p) && !mount_is_automount(p) && MANAGER_IS_SYSTEM(UNIT(m)->manager); +- + /* Mount units from /proc/self/mountinfo are not bound to devices + * by default since they're subject to races when devices are + * unplugged.
