I want to do something like
ALL ALL=/bin/mount -o loop -t ext3 $HOME/* $HOME/*
to allow users to loopback mount a filesystem image, but only in their
own home directory.
by doing, for example
$ sudo /bin/mount -o loop -t ext3 $HOME/imagefile $HOME/mountpoint
That one passes the value of $HOME to sudo and rule doesn't match.
Single quoting $HOME to avoid shell interpretation passes $HOME to
/bin/mount whichfails to understand.
I have set my /etc/sudoers to preserve the value of $HOME.
It will work with '/bin/bash' inserted but that seems wide open to
Is there any way to get sudo to use the value of $HOME in a rule?
