So, I'm pretty far from a kernel hacker, but I've got a project
I'm really wanting to get into.
What I want to do is put a layer on top of the filesystem to do
some kind of filename abstraction to rewrite a file path. I really just
want a place to look before it looks on the disk.
The idea is to have something kinda like plan9's bind command,
sort of a symlink that overrides filesystem paths and is valid for a given
process and all processes below it. For instance (from the bind manpage
To compile a program with the C library from July 16, 1992:
mount /srv/boot /n/dump dump
bind /n/dump/1992/0716/mips/lib/libc.a /mips/lib/libc.a
Of course, I'm not looking to do the yesterday stuff taking daily
filesystem snapshots, just the process-level rewriting.
Is this a completely crazy idea? If it's possible to do it
without rewriting huge parts of filesystems, I'd like to play with it
some. Any pointers?
