Hi,
I love aufs but wonder if it's kernel page cache friendly.
In my setup I have a shared folder with lot's of tools, libs, etc.
installed. I now mount this read-only to several locations and start the
tools from there. Does this result in reduced memory usage (as it would
be the case if I started the same tool several times from the same path
without using aufs)?
mount -t aufs -o br:/home/custom1=rw:/home/shared=rr none /home/merged1
mount -t aufs -o br:/home/custom2=rw:/home/shared=rr none /home/merged2
/home/merged1/tool
/home/merged2/tool
The program tool and its libs are of course not overwritten in any
of the custom paths.
BTW: Is aufs really no longer maintained anymore like wikipedia
(http://en.wikipedia.org/wiki/UnionFS) tells me? Which one is better in
terms of longtime support?
JRO is still turning out an update every Monday.
I would think that means the wikipedia comment is incorrect. ;-)
Mike
Thanks,
Corin
