If you start bitbake in memory resident mode and have buildhistory enabled, the command line it records in the commit in the buildhistory repo has the server's command line instead of what was invoked for the build, which isn't very useful.
Fix merged to master: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=3d4c64fb9ff33a074328c37c7803c13ecc95f689 http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=120810c50821919fd231cbd6d63cf27f67338f7a http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=4d1866bd28ddb6a951a9502bc09767221266745a We introduced a new BB_CMDLINE variable as part of this, but it's pretty low level and thus would probably only need to be documented in the bitbake manual.
