Hello,

Is it safe to add root to a group other than its default root group?

Or to change its default group to another one?

Or to add a user to the root group?

Mozilla Firefox has exec permission for root and its group, so I thought if root and user 1 shared the same group user1 could run the app, but this may not be safe.

Thanks for your help

Many thanks, Peeyush Maurya, for your answer!

In fact you can set root as owner and root as group and still use Firefox.

Firefox permissions are rather slack -- they are set to other: r-x.
I'll have to see what restrictions can be made.

Regards,

Please keep in mind that a user who is added to the root group will be granted rights to most parts of the file system.

It is not advised to add a user to the root group.

root on the other hand does not have to be added to a group to be able to execute a file.

You may change the group (chgrp) of the firefox directory to something like users or create a new group, say, firefox and add the users who would like to use firefox.

A more safe method is to

#chmod -R o+rx /path/to/firefox

That is, grant read and execute rights to everyone.

Thanks ppuru for your answer.

Firefox is set to o= r+x which doesn't look to me to be safe at all, but may be necessary.

I rather like the idea of adding a specific user for webbroswing.

Cheers,

hmmm ... what was I thinking while I typed that ... read safe=easier/quicker

Can i add a user to the root group and make sure that he does not have access to a particular file.
what about the capabilities of user in the root group. How does it differ from root.
