Are you also aware that you can configure devfsd to "EXECUTE" a given script whenever a device becomes available? See: http://www.gentoo.org/doc/en/gentoo-pda.xml (Code listing 2.6: Editing /etc/devfsd.conf) HTH, JZ -- [EMAIL PROTECTED] mailing list

Or hell, just schedule an rsync push/pull based on time intervals and system events. forget the whole nfs deal. On Thu, 2003-07-31 at 09:06, Paul K.

Re: [gentoo-user] OT: Good NFS for laptop?
I don't know about any good network file systems other than the few you have listed, but, have you considered that this kind of functionality isn't really what the nfs should be doing? Usually, this stuff relies on a set of tools that use nfs as a transport method. My only suggestion would be to use automount, which will auto unmount should the detination become unavailable, then run something that will occationally check for the sync destination to exist, and run a sync at a time interval you specify, on laptop resume, etc etc. I've attached a script that I wrote to check for the presence of my PDA on the usb port. Perhaps you can modify it to fit your needs. Cron it, whatever. It does, if I remember correctly, loop every 5 sec, so that will most likely need to be adjusted. If you come up with any solutions, I'd be pleased to hear:) I currently just backup my laptop by tar.gzing the home folder once every couple weeks, but I'd like to have it automated every time I plug in;) Paul K.

This sounds like a job for CODA, but people may say that's overkill. I
haven't yet used it myself but I should definitely do some exploring I
think.

As it turns out, rsync is quite a useful tool for this, although it's
obviously not a filesystem.
In my ~/.bashrc:
alias home-up="rsync -avz -e ssh --exclude downloads/ ~/ master:~/"
alias home-down="rsync -avz -e ssh --delete --exclude downloads/ --exclude
ogg/ music/ master:~/ ~/"
I type 'home-down' when I'm taking my laptop away, and 'home-up' when I
bring it back to sync with other things. I don't care to have a bunch of
stuff cluttering up my laptop so I exclude a few directories when
downloading.
