Comment 1 Tim Waugh 2007-06-25 10:53:04 EDT
/etc/mtab shows how the filesystem was mounted using mount(8).  There's not much
we can do about the kernel re-mounting read-only.
Comment 2 Rafal Wijata 2007-07-02 03:40:03 EDT
I guess mount should not use /etc/mtab but /proc/mounts
Isn't that *BSD going this way?
