Right. I believe that it causes problems, so I'd like to avoid it.
As you said -- I want to keep the bootloader's configuration and
fstab the same. But I want to be able to do it dynamically: have two
different entries for booting (I use GRUB) and two different fstab
files as well. Maybe I wasn't clear enough -- if I boot kernel a,
then, as you said, the read-only filesystem gets remounted according
to the first variant of the fstab file, which must correspond to the
boot options. If, however, the kernel b get loaded, it always means
that the second version of fstab must be used instead. And never
vice versa.
Here's the point: can I include an init script that would simply
switch between those two files *before* the remounting takes place?
Or, if you like, does that remount happen before init even gets to
do its work? In that case, I'm clueless ...
NB: That is only one and the very same disk put into different
places.
