src/slave/containerizer/mesos/launch.cpp (lines 64 - 65) <https://reviews.apache.org/r/31444/#comment142621> "must be relative to" is really "is interpreted as relative to" right? Just wanted be sure clarify: 1) Should the user specify an absolute path with a preceding /? 2) The directory path as observed by processes outside the choot jail is `path::join(rootfs, directory)` right? src/slave/containerizer/mesos/launch.cpp (lines 259 - 260) <https://reviews.apache.org/r/31444/#comment142612> "This must be an absolute path" As in, if the flags specifies a path without a preceding slash this throws an error? This is not enforced is it? - Jiang Yan Xu On June 22, 2015, 9:38 a.m., Ian Downes wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
