    Default How does encrypted home folder work?

    I'm guessing that a file is created as a loopback device and encrypted (using LUKS?)

    What is the mechanism used at user login to decrypt and mount the encrypted $HOME and to re-encrypt it at logout?

    I confess an ulterior motive here - SWMBO has recently got her hands on an Acer Aspire one running Linpus Lite and there's absolutely no security on it

    Personally I'd dump Linpus and put on openSUSE but it's her box and she likes the simple interface that Acer have supplied so maybe I can set up the encrypted $HOME as YaST does for openSUSE if I can find out what to do.

    Any hints, links, HOWTOs that don't overload my poor burned-out grey cells with spurious information greatly appreciated.

    I would simply set up a new user in my computer with encrypted home, with
    YaST, then find out how it works.

    I use encrypted partitions, but not home. I think it creates a loop mounted
    encrypted filesystem of the size you say, in the existing home. It probably
    needs some mechanism when login in.

    Whether automatically mounted or if you prefer to custom mount a loop device, note that there is an encryption option

    Code:
    man losetup

    Fine, now how does it get mounted at login?

    No idea. Investigate how YaST / Suse does it. Then you tell us, I'm curious :-)
