No. He wasn't rude. Not a bit. He simply was - as most of the time here
- very specific, terse and up to the relevant technical points. And
yes: I miss Michel's postings here a little bit. He's a pro, and I
definitively trust him a lot when he's commenting here or elsewhere.
Here's an example of what might be understood as rude. It was written
by me, years ago, on this list:
"Situations like that is why I say that Debian-Linux does not work for
people with a girl-friend or a family, or for folks who need to get a
job done on a computer in a reasonable amount of time. Or for folks who
simply like watching shadows on the wall (John Lennon :) or the stars
above them.
I'd guess it's a system for folks not knowing what to do with their
lives if they had a working OS on their computer."
Whole message:

I admit: I miss postings like that previous one a bit ... :)

No worries, Adrian: I'm immensely grateful to all Debian developers,
maintainers etc. for their work - and to every single one of them. I'd
suggest to not destroy the fun of working on it by being too sensitive
about what people *might* have had in their minds when posting here ..
Love you all .... :)
