I meant e2fs module; yes that's quite near to kernel :). I was
thinking about some sort of file attribute (though it'd more that just
a flag); I think it would quite near to ACL, implementationnally
speaking: it's just a bunch of data that gets associated with an
inode, and which is interpreted by the fs-driver when accessing the
file (here, the directory)

BTW, thinking about other FS's: there are people booting over network,
tuhs having their root-FS a NFS one. But I do not think that is a
problem. Any comment ?

About ACL's: they seem to be planned since quite a long time, but
there is still not much code supporting them in 2.1.43 kernel. I think
I'll have to mail Remy Card to find out about that; it could help much.

About amd: I just knows it does exist, but not much more; especially,
why is it useful to automount ? just to save the kernel-allocated
memory used by the mounted FS ?

The solution of putting everything into /usr/etc is IMHO less general
than having a search path, be it in apps or in FS-driver.
