Thank you!
Everything works fine, though during installing I successfully booted to diag mode
. It took some time to find the menu point to get out of it. And I was able to telnet into the Kindle. (Bad part: when I wanted to log off, I realised in spite of typing, nothing happens, so it seems it would have not help me at all... Login screen is nice though.) So both Constantia for Knidle and DejaVu Eink seem OK fonts.
(And it was years ago the last time I used ifconfig down
)
