As you said fine, I need to allow cups to write into that directories
(including /root) or into a $HOME/cups-pdf-docs directory to disallow
cups all control over $HOME directory.
If I remember well, cups is launched as root user (where a test I had
done some days ago because were a "cups-pdf" prerrequisite - don't
remember now).
How can I solve the issue with home directories?
If anybody knows how to, I would like to solve the problem in this form:
1) Allowing cups writing into home directories or especific
subdirectory into $HOME.
2) Enablilng SELinux as restrictive I can (is my laptop and I want to
learn a more about SELinux and apps issues.
As a start you might try:
# setsebool -P cupsd_disable_trans 1
This would turn off SELinux protection for the cups daemon, whilst
leaving you able to have SELinux turned on for everything else.
An alternative that might be worth trying would be to change the context
of any directories you want cups to be able to write to, something like:
# chcon -t print_spool_t $HOME/cups-pdf-doc
Not sure if that'll work though.
