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. 2010-04-10 01:44:28 +04:00			`# Copyright (C) 2009-2010 Red Hat, Inc.

Add default udev rules. Update dm-ioctl.h comments. 2009-08-03 22:44:54 +04:00
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. 2009-10-26 17:29:33 +03:00			`DM_RULES=10-dm.rules 13-dm-disk.rules 95-dm-notify.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. 2012-02-24 13:53:12 +04:00			`ifeq ("@BUILD_LVMETAD@", "yes")`

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 2010-04-10 01:34:25 +04:00			`vpath %.rules $(srcdir)`
