I don't think you can feasibly hve /etc shared just yet.
However, it would be good if /, /etc, /bin, /lib could be mounted
read-only, eg for security reasons, or booting from CDROM.
/etc/network/ifstate - is just one problem here.
others are:
/etc/mtab - can be solved to certain degree with symlink to
/proc/mounts, however this is a can of worms.
/etc/resolv.conf - some daemons need to update this, eg. pppd,
dhcpd
/lib/modules/x.y.z/modules.* - this is horrible IMHO, it really lives
under /var.
In all these cases, the files are required or potentially required
before /var has been mounted :-(.
Looks like the /mem proposal might be a good idea...
or /var_small maybe???
On some systems this could be on ramdisk, on others it could be part of
the harddisk.
