Chown in sudoers file : Safe or not?
Solution 1:
Yes.
From man sudoers:
If a Cmnd has associated command line arguments, then the arguments in
the Cmnd must match exactly those given by the user on the command line
(or match the wildcards if there are any). Note that the following
characters must be escaped with a '\' if they are used in command
arguments: ',', ':', '=', '\'. The special command "sudoedit" is used
to permit a user to run sudo with the -e option (or as sudoedit). It
may take command line arguments just as a normal command does.
