[lfs-support] Partial explanation for a test fail in sudo

[Hazel Russman]

For the last three BLFS versions, I have noticed a single failure in the check tests for sudo. The test that fails is testsudoers/test3.

I have now discovered that this failure only occurs if the tests are carried out by root in chroot. For an unprivileged user, all tests pass.

Because of the usefulness of sudo in installing packages, it often gets built as an appendix to LFS using the chroot environment. If you do this, you can expect the failure.

I have never built sudo and plan never to do so. I'm the only one that uses my computers, so who am I protecting it from? I use root. One must be just as careful when using sudo anyway. Have I screwed up? Once or twice since I built my first LFS in 2004, but that's what backups are for.

I can now be more specific. It isn't doing the tests in chroot that causes the error, it's doing them as the root user. If I su from root to myself and do the build and tests like that, they all pass.
