If that is the case, then it is wrong to write "installable on 512MB of
storage" in the FAQ webpage.
At the very least, you should write a value that works without the installation
of additional ports, etc., and if you can make it user-friendly,
you should change it to the minimum value that can be used normally, excluding
the user area.

In my amd64 environment, with no additional software installed,
the results of "df -h" were as follows.
hoge# df -h
Filesystem Size Used Avail Capacity
Mounted
/dev/sd0a 1.9G 91.5M 1.8G 5%
/
/dev/sd0g 4.8G 18.0K 4.6G 1%
/home
/dev/sd0d 1.9G 6.0K 1.8G 1%
/tmp
/dev/sd0f 9.7G 1.3G 7.9G 14%
/usr
/dev/sd0e 3.9G 8.0M 3.7G 1%
/var
Taking this as an example, this means that about 1.4 GB is being used.
Of course, the data capacity required for any partition increases as it is used,
so why not rewrite the FAQ as 1.5 GB as a minimum value
(but not recommended for use as a comfortable environment)?
