Make installation directories overridable at runtime. This makes it possible to run tests that need access to installation directories, such as the rundir, without having access to the actual installation directories (/var/run is generally not world-writable), by setting environment variables. This is not a good way to do things in general--usually it would be better to choose the correct directories at configure time--so for now this is undocumented. 2010-11-29 12:28:26 -08:00			`import os`
dirs: dbdir default must be based on sysconfdir. Some in-tree and out-of-tree code sets the OVS_SYSCONFDIR environment variable to control where /etc files go (mostly for test purposes). When the database directory (dbdir) was split off from the sysconfdir, the configure-time default continued to be based on the sysconfdir, but overriding the sysconfdir at runtime with OVS_SYSCONFDIR didn't have any effect on the dbdir, which caused a visible change in behavior for code that set the OVS_SYSCONFDIR environment variable. This commit reverts that change in behavior, by basing the dbdir on OVS_SYSCONFDIR if that environment variable is set (but the OVS_DBDIR environment variable is not).
