You can put your user in the group adm, here my /var/log/syslog is owned by root:adm with rw for root and r for adm.
Otherwise if you want to open a root gui from a user session, just enter this
Code:
#xauth merge ~user/.Xauthority
#gui-app
or if you want, you can use sux
Code:
user@host:~$ sux gui-app
I don't know root-tail but I bet its pretty safe (tail -f log)
