Update install rules for udev. Fix unwanted modification of $(top_builddir)/make.tmpl. Using dependency rules to install rules for udev. There is minor problem, with concurent usage of builddir and srcdir could lead to missuse of 10-dm.rules which could be found in VPATH from different builddir. However current solution uses intermediate target so the generated 10-dm.rules exists only for short period of time during make install execution.

udev: udev rules cleanup Remove executable path detection in udev rules and use sbindir that is configured, but still provide the original functionality by means of 'configure --enable-udev-rule-exec-detection'. Normally, the exec path for the tools called in udev rules should not differ from the sbindir used, however, there are cases this is necessary. For example different environments could be assembled in a way that these path differ for some reason (distribution installer, initrd ...). This functionality is kept for compatibility only. Any environment moving the binaries around and using different paths should be fixed eventually!

include $(top_builddir)/make.tmpl
Several changes to udev support code: - we have these levels when the udev rules are processed: 10-dm.rules --> [11-dm-<subsystem>.rules] --> [12-dm-permissions.rules] --> 13-dm-disk.rules --> [...all the other foreign rules...] --> 95-dm-notify.rules - each level can be disabled now by DM_UDEV_DISABLE_{DM, SUBSYSTEM, DISK, OTHER}_RULES_FLAG - add DM_UDEV_DISABLE_DM_RULES_FLAG to disable 10-dm.rules - add DM_UDEV_DISABLE_OTHER_RULES_FLAG to disable all the other (non-dm) rules. We cutoff these rules by using the 'last_rule', so this one should really be used with great care and in well-founded situations. We use this for lvm's hidden and layer devices now. - add a parameter for add_dev_node, rm_dev_node and rename_dev_node so it's possible to switch on/off udev checks - use DM_UDEV_DISABLE_DM_RULES_FLAG and DM_UDEV_DISABLE_SUBSYSTEM_RULES_FLAG if there's no cookie set and we have resume, remove and rename ioctl. This could happen when someone uses the libdevmapper that is compiled with udev_sync but the software does not make use of it. This way we can switch off the rules and fallback to libdevmapper node creation so there's no udev/libdevmapper race.

DM_RULES=10-dm.rules 13-dm-disk.rules 95-dm-notify.rules
LVM_RULES=11-dm-lvm.rules
Add skeleton for lvmetad udev rules - 69-dm-lvm-metad.rules. Why using the order 69: - Storage processing in general happens in 60-persistent-storage.rules, including the blkid call that adds some usable information we can use for filtering and speedup (these rules are part of upstream udev and the order is preserved on most distros) - There's still some other storage-related processing done after 60-persistent-storage.rules in general. These might add some detailed storage-related information we might use to filter devices effectively (e.g. MD udev rules, ...). - We need lvmetad rules to be processed before any consumers can use the output - so the metadata cache is ready soon enough (e.g. udisks rules). - There's no official (upstream udev) document about assigning the order, so this number is chosen in best belief it will suit all scenarios.

Use vpath instead of VPATH. Usage of VPATH makes troubles when used within $(builddir). Not only source files are being found through VPATH, but targets as well. (make --debug=v) Thus if user builds the code in $(srcdir) and also in some $(builddir) he gets mangled results as some generated files (i.e. .export.sym) are 'reused' from $(srcdir) instead of $(builddir). This patch switches to use vpath were we could explicitly name suffixes that should be looked via vpath - we must take care, we do not generate files with these suffixes: .c, .in, .po, .exported_symbols

udev+systemd: make pvscan --cache -aay run as systemd background job from udev The new lvm2-pvscan@.service is responsible for on-demand execution of "pvscan --cache --activate ay" which causes lvmetad to be updated and LVM activation done if the VG is complete. Also, use udev-systemd mechanism to instantiate the job as the lvm2-pvscan@$devnode.service on each newly appeared PV in the system. This prevents the background job to be killed (that would happen if it was directly forked from udev rule - this behaviour is seen in recent versions of udev with the help of systemd that can track detached processes - the detached process would still be in the same cgroup). To enable this official udev-systemd protocol for instantiating background jobs, use new --enable-udev-systemd-background-jobs configure switch (it's disabled by default). This option is highly recommended wherever systemd is used!

makefiles: avoid using vpath for rules files Fixing vpath usage as it has been checking for existance of generated file also in the $(scrdir) e.g.: No need to remake target '10-dm.rules.in'; using VPATH name '...' If the $(srcdir) had been also $(builddir) and contained already generated rules file, it's been used instead generating new one. (See: http://make.mad-scientist.net/papers/how-not-to-use-vpath/)
