Subject: * Add a MOUNTOPT config record in the config log. This is saved as a
X-Git-Tag: v1_7_0_51~2^7~479
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=510f39f03f9c77649ef81ca2aab5b8c105a3d89b;p=fs%2Flustre-release.git

* Add a MOUNTOPT config record in the config log. This is saved as a
profile, which ll_fill_super uses to determine which MDC and LOV
devices to connect to.

* Lconf creates a cleanup log, too.,

* replay-single.sh updated to use current 0-conf scheme. It isn't
pretty yet, but getting there.
