Thanks! I have briefly tested this: the patch does the right thing in the failure case, and let's hope that it doesn't break anything else.

Please install it in the master branch -- instructions are on http://www.bddebian.com:8888/~hurd-web/rules/source_repositories/, please read that page carefully before pushing to Savannah, or ask me if you need help. Even better: first publish it in a throw-away repository on flubber, or in a private branch on Savannah, until we get all that new Git stuff going correctly.

When running via rpctrace, a program like this will fail with the specified error message, while it won't error and will finish correctly when running directly.

#v+
if (setregid (getegid (), -1) != 0 ||
setreuid (geteuid (), -1) != 0)
{
perror ("failed to drop real uid/gid");
exit (1);
}
#v-
