Thanks Nado,
this was the hint I needed. I compared the fstab entry with the one of
my new Arch install and noticed that it had an entry for /. Once I had
added the entry root was mounted rw as it should be. I don't remember
editing fstab recently so I don't know how this came to be. Maybe the /
entry wasn't needed for a while? I remember a change a couple months
back that suggested the removal of fstab entries.
Anyway, what's the explanation for this behavior? Is / only mounted (and
remounted) ro by default? I guess it's the 'defaults' entry, which
includes rw, that leads to the remount as rw. Is it normal that it is
necessary?
Sorry Nado for only replying to you personally the first time, I'm using
a new mail client that's not as clever as the previous one and I need to
manually tell it to reply to the list, which I tend to forget.
Regards,
Philipp

Could you show us your /etc/fstab file ?
