1) Look Ma... no cpio. During my first attempt to build a kernel, it
died because the process couldn't find "cpio". I ran "emerge -1 cpio"
and tried again, finishing successfully. "emerge -p --depclean" wants
to remove it, which should not be happening. To overcome that I ran
"emerge --noreplace cpio" which put cpio into my world set, keeping it
safe. Why is this happening in the first place?
2) When building xorg-server I got a news item about the "suid" flag
soon no longer being default for xorg-server. I forced it manually on
my laptop and desktop. The other 3 options were...
* systemd... no thanks.
* elogind... with PAM doing the authentication... no thanks. I've
tangled with PAM in the past once too often.
* some memory-heavy "desktop environment" on my 3-gigs-ram-laptop...
no thanks.

Discussed here: https://bugs.gentoo.org/731666
and here: https://bugs.gentoo.org/696840
Summarised, this dependency is triggered by CONFIG_IKHEADERS, which has been
configured too obscure to pull in cpio for everyone (hence the WONTFIX status
for the latter bug report).

My apologies for a small typo. This should read "...which has been _determined_
too obscure...".

Thank you. That's a relief. I was afraid that I had missed something
during the install process.

There is a way to run rootless X without elogind:
For Nouveau and Intel video cards except xorg modesetting driver:
https://wiki.gentoo.org/wiki/Non_root_Xorg
For AMD video cards and/or xorg modesetting driver:
https://forums.gentoo.org/viewtopic-t-1092792-start-0.html

There was some debate on Gentoo-Dev regarding this a while ago ([1] is the
discussion, and [2] is the final announcement). It was suggested in [3] that
disabling `suid` is a step forward, as running X as root is "anti-pattern",
which is probably correct for most cases. Nonetheless, as you do not want to use
any of the proposed alternatives (XDM or `startx` with systemd/elogind), just
re-enable `suid` and use X as it always has been used in the past, however
"anti-UNIX" that may be.
The other fundamental reason for this change was security. As described by Dale
in [4], from a user's perspective, it should be a reasonable expectation that
the defaults, especially for such a widely used package, are secure.
