Andriy Gapon 495ec94fd7 MFV r303082: 6391 Override default SPA config location via environment ... illumos/illumos-gate@ae24175b2b ae24175b2b https://www.illumos.org/issues/6391 When using zdb with non-default SPA config file it is not convenient to add -U <non-default-config-file-path> all the time. This commit introduces support for setting/overriding SPA config location via environment variable 'SPA_CONFIG_PATH'. If -U flag is specified in the command line it will override any other value as usual. 64d7b6cf75 Reviewed by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed by: Richard Yao <ryao@gentoo.org> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Reviewed by: Will Andrews <will@freebsd.org> Reviewed by: George Wilson <george.wilson@delphix.com> Approved by: Robert Mustacchi <rm@joyent.com> Author: Cyril Plisko <cyril.plisko@mountall.com> MFC after: 1 week		2016-07-20 10:06:56 +00:00
