In debian/initramfs/scripts/init-premount/brltty there's:

  cp /proc/mounts /etc/mtab

This is wrong, /etc/mtab is supposed to be a symlink to
/proc/mounts. Please remove this line.

Hello,

At last I get some time to dig more about it.

Well, it is not in my test (adding break=mount to the kernel command
line). Maybe your setup is different?

/etc/mtab is pointing to /proc/mounts in the real system (after
booting initrd finished), it shouldn't be a normal file inside the
initrd either.

Ok, then which package is supposed to build that symlink, so we can add
the symlink there and remove the copy in brltty?

/etc/init.d/checkroot.sh of package initscripts creates the symlink,
the code that does that is inside /lib/init/mount-functions.sh
(function mtab_migrate).

Err, aren't these scripts in the installed root, not in the initramfs?

initscripts doesn't currently introduce scripts in initramfs.  Do we
really want to make that package build the symlink, not another one?
(particularly since switching from sysvinit to something else is being
considered).
