Subject: If ld.so loading fails inside execve, uprintf a message to report this
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=22c1e09064b1e80904e60b6dae4e97e7b6676b39;p=openbsd

If ld.so loading fails inside execve, uprintf a message to report this
before the SIGABRT kills the process.  This clarifies the failure mode
(and resolution to take) when a dynamic executable is run while /usr
isn't mounted.  ok miod kettenis
