Configure will also test the container engine by trying to run the
selected SDK image.
This may make the first configure a bit slow, as it downloads the image,
but after that the SDK will be cached locally.
Debian-like distributions install AFDKO's executables into libexec and
provide an `afdko` helper to call them.
Python's pip installs the executables in bin.
Let's support both.
Opening file in append mode sets the offset to the end of the file prior
to each write. This allows user to append tags/notes to the log file
just before interesting events, e.g.:
local $ ssh ivyl@test
test $ echo "!!! FOCUS CHANGE" >> ~/steam-XYZ.log
The log file is deleted just before we open it anyway, so there won't be
any leftover content from previous session.
