Hm. I don't find any library/package which has a similar name. I guess
you mean libglib, but I might guess wrong.

For reference, here's what apt show has to say about blueman on my

No glib-x11 around, either...

OK, I see. Sorry if I sometimes ask things which may be obvious to

Hm. Sorry. I can't find that package.

Yes, but what/where is glib-x11? No package with this name, no package
containing a file named like this (all on Debian Stretch, aka 9, aka
stable). What am I missing?

Yes agreed, but... where is glib-x11? Is blueman complaining? in which

I see. I haven't much experience there: I'll have to look that up.
Perhaps someone with more experience can chime in here.

Yes. It seems that for some reason, the init script is trying
to bring up the device under its old name. So you might try to
boot once appending " net.ifnames=0" to your kernel command
line (I forgot how that is done with LILO, but I guess you know).

The alternative would be to debug /etc/init.d/networking,
perhaps by sneaking a "set -x" somewhere at the top of the

"ifup -a" should work then too...

To be fair, hardware beneath this has changed *a lot*, although we
perceive those boxes as just "PCs" from the outside. And nowadays
network interfaces, mass storage, etc. "come and go" even on low
end hardware. So I do understand how that has come. But OTOH, learning
and hacking has become more difficult.

This is a good idea, but it has its downsides too: Whenever you
exchange the network card (or move the disk to another "identical"
box), things stop working. Sometimes it does what you want,
sometimes it doesn't :-)
