Its a demo of the theory (but quite usable). Doing supermount in kernel is suprisingly hard, the locking and races you get into are not nice at all - ask Juan about that ^ permalink raw reply [flat|nested] 4+ messages in thread

I realize it will be hard if I start from scratch. Since I was planning to do it in 2.5.x it will be easier for me to learn how to avoid the problems that plague the older versions.

I haven't gotten that far, yet. How well it works depends a lot on how much of the information about the disk can be read by Supermount 2 when the disk is inserted. > > 3) Built-in support for packet-writing.
