Never seen that.  My reading of the code is that this can happen if
initChild (in build.cc) fails (see the occurrences of SysError there.)
Do you see one of these error messages before?  Could it be that the
daemon is not running as root, and so chroot(2) fails?

No, that’s expected: the log file for byc1s… is called by/c1s….

HTH,
