[Buildbot-devel] Step fails only under Buildbot

[Mihai Martalogu]

Depending on how you launch the buildbot slave, you might not have the same
environment as on the CLI. In our setup, we use an @reboot rule in the
crontab for launching the buildslave process, and by default it doesn't
have any of the variables set in .bash_profile or .bashrc (I'm assuming
you're using bash).
We work around the issue by setting any custom variables we need in our
.bash_profile, and launching the buildslave in the crontab via a "bash -l",
which will load the .bash_profile. Like that the environment is consistent
across buildbot/cli. If you use .bashrc, it's a bit more complicated (but
doable).

Good luck,
Mihai
