Dear list,
I just want to share the two most important things I learned yesterday:
1.) I can "delete" files for which I do not have write permissions, if
the containing directory is writable by me:
|| The system deletes files automatically when their reference
|| counts drops to zero. The owner of the file doesn't matter.
https://superuser.com/questions/369493/
2.) On logout, the user's processes are not terminated because they had
been spawned from a common "ancestor" process, but because they have
a common "session id" (SID).
As I have not been able to find a detailed documentation of what's
happening on quitting a session, I think about writing a summary of the
related mechanisms in the pre-systemd world. Thus, I'd like to ask you
for hints about related resources, also regarding the "backgrounding"
and "detaching" of processes
Thank you and libre Grüße,
Florian
