When i download Gentoo Linux the file name might be called something like: livedvd-amd64-multilib-20160704.iso
This might be fine if you just want that file and want to use it straight away.
But lets say like i just did downloaded multiple linux distributions because i want to test them out so i have like 10-20 iso files or what ever.
Then later one when i see the file name livedvd-amd64-multilib-20160704.iso i have no idea what distribution that was.
The other distributions i have downloaded all seem to start with the name of the distribution in the file name. I Think Gentoo Linux is the only one yet that does not.
So would it not be better to use a file name like this?: gentoo-livedvd-amd64-multilib-20160704.iso
