Thank you for your explanations. I made some progress in my
investigations: the problem seems to be a change in the "su" command
from f32 to f34: my personnal umask is 0077 and I use to log as root
using the command "su -". Until f32 this way of doing gave a root
login with all environment variables of the root account (including
the UMASK). As far as I can see this is no more the case in f34....
Where is the config for the "su" command? And is it possible to change
this behavior?
umask isn't an environment variable. It's a kernel setting for the
process. Why are you using "su" anyway instead of "sudo"? (I don't
know if that will change anything regarding the umask, but it's better
to not have a root password.)
I am using su instead of sudo because:
1- I am a dinosaur from the Unix times...
2- the times are not so ancient when you performed a fedora install you
where asked to set a root password...
3- since these times, appeared the "dnf system upgrade" where the
previous config is continued and my systems are still using a root
password and have no sudoers config... (for how long will it last and
will the packagers inform us of a major change for this?)
4- I found strange the sudo system for it allows to give permissions on
the machine to people who may have a (very) weak password...
5- At the university they have installed users'machine with ubuntu and
sudo system, they gave me all permissions on my machine and I have to do
a "sudo bash" if I want to make changes on it.... I have to change the
umask if I don't want to limit changes to root only..., moreover the
bash history becomes a mix of my commands as a simple user and the
commands I run as root... it is a hotchpotch of commands which becomes
quickly unusable...
6- there are, maybe, some other inconveniences...
Maybe this will help:
https://unix.stackexchange.com/questions/328104/setting-umask-for-su-user-command
I'ill study this... But, I think I'll add to the /root/bashrc
"umask=0022" hoping that it will solve my problem.
