issues su/sudo and more

[arnaud gaboury]

I run one Fedora Atomic 30 desktop and one server. I am lfet with two
issues on these machines.

1. On server:

---------
gabx@poppy➤➤ ~ % su
zsh: permission denied: su
gabx@poppy➤➤ ~ % sudo -i
[sudo] password for gabx:
root@poppy➤➤ ~ #
-------------------------
Is it the expected behavior? I could run su a few days ago.
Below some info:
----------
# cat /etc/sudoers
root ALL=(ALL) ALL
%wheel ALL=(ALL) ALL
#includedir /etc/sudoers.d

# cat /etc/sudoers.d/gabx
gabx ALL=(ALL) TYPE=sysadm_t ROLE=sysadm_r ALL
# semanage login -l

Login Name           SELinux User         MLS/MCS Range        Service

__default__          unconfined_u         s0-s0:c0.c1023       *
gabx                 sysadm_u             s0-s0:c0.c1023       *
root                 system_u             s0-s0:c0.c1023       *

gabx@poppy➤➤ ~ % id -Z
sysadm_u:sysadm_r:sysadm_t:s0-s0:c0.c1023
------------------------------------------------

2. On Silverblue desktop, I can't start the system anymore with selinux
enforced. I had to edit kernel command line with selinux=0 to boot, then
edit selinux config to disable.
How can I debug and solve this issue?


Thank you for help.
