x11docker ToDo notes

Actually to fix

--pulseaudio=socket fails if x11docker was started with sudo.
--iglx now works with --xorg -> report at kata
--exe: Give notes for invalid options.
--update: Check if installs into /usr/bin or /usr/local/bin. Do not install other files then.
--password, --install, --update, --cleanup, etc.: give note about dropped options. Maybe change to $1 mode without --
check all --init= in all backends rootful and rootless.
- checked:
  - rootful docker: all
  - rootless podman: systemd, openrc
  - rootful podman: openrc
  - rootless nerdctl: openrc
  - rootful nerdctl: openrc
--user: Check in all rootless modes, maybe disallow except for --user=root.
--user=root --home in rootless docker and nerdctl: Set up HOME in host user ~/x11docker?
--backend=podman rootless: disallow --home for different --user.
--init=systemd: cgroupv2 support #349

--kwin-xwayland: broken? Xwayland says: "missing wl_shell protocol". Deprecated yet.
--gpu --webcam adds user to group video twice.
docker-for-win: DOS newline mess in error() #219.
docker-for-win: Double entries in log.
--install/--update: first install shows entire CHANGELOG.md. Should only show most recent release notes.
replace find in containerrootrc, missing in fedora images.
error message window in Wayland fails: xterm: no display. x11docker should use konsole or xfce4-terminal.
--env: check escapestring results in containerrc, some ugly strings are not escaped well

--init=systemd: check systemd warnings on x11docker services
--printer: regard host environment variable CUPS_SERVER. Maybe already done by lpadmin.
pspid(): On some systems (busybox) ps -p is not supported
--runtime=kata-runtime: x11docker/lxde needs --init=systemd, why? Sort of menud issue.
--runtime=kata-runtime --nxagent: ALT-GR works wrong.
myrealpath(): If realpath is missing, the path argument is returned without resolving.
--interactive --init=runit|openrc|sysvinit: no job control in shell
--interactive not possible without winpty in WSL and Cygwin
--interactive --enforce-i fails. Issue is subshell containershell & in main, would work without it.
--group-add: gid 101 for both possible: messagebus and systemd-journal, works nonetheless.
--keymap does not work on tty with --kwin and --kwin-xwayland. No idea how to set it.
--wayland --user: wayland socket access denied due to XDG_RUNTIME_DIR file access permissions

x11docker/check: Print several checks in terminal before running gui
x11docker/fluxbox on arch host: background can miss, sometimes no context menu. Where is the difference to other hosts?
--sudouser: su to root in void containers fails.
elogind in alpine: su does not take effect. missing policykit? pam corrupted by x11docker?
elogind in void container: loginctl is empty. ck-list-sessions, too.

kwin_wayland needs CAP_SYS_RESOURCE even if running nested
--xpra --desktop --xdummy: --size modeline does not work, might not even appear in xrandr although set in xdummy.xorg.conf
Xwayland does not support X over IP (-listen tcp)

Xwayland does not always sit at 0.0 on multiple outputs. https://bugzilla.redhat.com/show_bug.cgi?id=1498665
--kwin*: wrong fullscreen and crashes in gnome-wayland, strange in weston, WAYLAND_DISPLAY="" does not help, probably bug in kwin
scale>1 Xwayland in Weston is too large (Xwayland bug), rendering issues on tty (switching scaled/unscaled Xwayland on keyboard/mouse events). https://bugzilla.redhat.com/show_bug.cgi?id=1498669

--cleanup: avoid hardcoded paths
support --exe --user ?
avoid losing dockerstopshell from process tree
avoid losing hostexe from process tree
dockerstopshell does not react if fifofile is deleted.
dependency wiki: Cygwin packages
capsh: replace su with capsh? (missing in alpine) But how to trigger login?
x11docker/check: palinopsia: check video RAM size with glxinfo, adjust requested RAM size.
further checks of /etc/pam.d
further checks of multimonitor behaviour
--init=s6-overlay: find better solution then sleep loop for empty CMD
--init=s6-overlay: check possible shutdown routine for timetosaygoodbye
--init=s6-overlay: closer check of needed capabilities
fedora: SElinux issue: --security-opt label=type:container_runtime_t: need more restrictive setting to just allow socket access. https://unix.stackexchange.com/questions/386767/selinux-and-docker-allow-access-to-x-unix-socket-in-tmp-x11-unix
