it's simple:
More simple when you tell it ;-) Thanks a lot, i will try it tonight !
it doesn't have chance - must work :)
I wish it's helpful, doing this doesn't just save space but saves time -
you have to upgrade software once.
So preserving consistency, which is the most important when you have lot of
diskless stations !
exactly. i'm using just NetBSD 1.5 (uses LITTLE memory) + Xserver, so
there are almost no updates, but anyway - it's stored once.
you may like to make /etc-common directory and put most of files there, and
symlinks in each station's /etc
In fact, it makes me think that we miss a concept in mount, or at least i
don't know it currently :
imagine a -tl (TransparentLayer) option for mount, allowing to mount multiple
source to the same directory, for instance /etc :
there is already such think - mount_unionfs
but i don't use it.
if you mount over some directory - it's original contents (like my /etc/rc
doing exec /systemrc) gets hidden.
mount -r yournfsserver:/basic/etc /etc
mount -tl -r yournfsserver:/TypeX/etc /etc
mount -tl -r yournfsserver:/StationY/etc /etc
mount_unionfs
but i don't know how stable it is.
When you want to change something, you add a rw TransparentLayer :
mount -tl yournfsserver:/StationYchanges/etc /etc
So that changed or added files are only stored in this rw partition, thus
very small and easy to manage.
This would be a kind of partition inheritance, like in object languages...
Dreams are allowed :-)
try mount_unionfs
