[Fedora-packaging] .desktop and permissions for using usb?

[Simone Caronni]

Hello,

same as the precedent mail, don't know if it's what you are requesting but
maybe you can look at "consolehelper".

You place your binary in /usr/sbin and link to it in /usr/bin with
consolehelper to have a graphical prompt for the root password upon
execution.

For example (bat from bacula package):

[slaanesh at 3zpc0560 ~]$ ls -al /usr/bin/bat /usr/sbin/bat
lrwxrwxrwx. 1 root root      13  5 dic 15.18 /usr/bin/bat -> consolehelper
-rwxr-xr-x. 1 root root 1376520  5 dic 15.13 /usr/sbin/bat

[slaanesh at 3zpc0560 ~]$ cat /etc/security/console.apps/bat
USER=root
PROGRAM=/usr/sbin/bat
SESSION=true
FALLBACK=true

[slaanesh at 3zpc0560 ~]$ cat /etc/pam.d/bat
#%PAM-1.0
auth       sufficient   pam_rootok.so
auth       sufficient   pam_timestamp.so
auth       include      system-auth
session    optional     pam_xauth.so
session    optional     pam_timestamp.so
account    required     pam_permit.so


Regards,
--Simone
