From: mornfall@sourceware.org To: lvm-devel@redhat.com, lvm2-cvs@sourceware.org Subject: LVM2 ./configure.in daemons/Makefile.in daemon ... Date: Wed, 31 Aug 2011 11:32:00 -0000 [thread overview] Message-ID: <20110831113159.4167.qmail@sourceware.org> (raw) CVSROOT: /cvs/lvm2 Module name: LVM2 Changes by: mornfall@sourceware.org 2011-08-31 11:31:58 Modified files: . : configure.in daemons : Makefile.in daemons/common : daemon-server.c test : Makefile.in test/lib : aux.sh test.sh Added files: daemons/lvmetad: Makefile.in Log message: A compromise integration of LVMetaD into the build: I have kept all the daemon/common code in a single libdaemon.a, which is completely private. This is currently linked into the lvmetad binary, and will be linked into LVM (the client part, since static linking only picks up only symbols that are actually used). I have also added --enable/disable-lvmetad to ./configure; although the current default is off, I expect this to be flipped to on shortly. There's no LVM-side support yet, but when there is, even when built, it'll still need to be enabled by an lvm.conf option.
