* /proc/cmdline -> /proc/2/cmdline (process 2 is usually gnumach)
This is not perfect, as the format of /proc/cmdline and /proc/*/cmdline
are different on Linux. Namely, the latter includes NUL bytes to
separate subsequent arguments, while the former contains only spaces
and a trailing newline.
* /proc/mounts -> /etc/mtab (push the problem to mount)
Among other things, many parts of d-i want /proc/mounts. Implementing
it the right way is non-trivial, though. In the meantime, we publish a
symlink to /etc/mtab so that the user can fake it in whatever way they
want. Furthermore I hope to be porting busybox mount soon, and use it
to manage the mtab.
