Re: [9fans] P9p's mount(1) on linux

[Uriel <uriel99@gmail.com>]

Thanks for your reply, but I'm not clear what you mean: should p9p's
mount check the kernel version? or are you talking about 9mount?

By the way, where can one find the git tree with the latest v9fs? I
was googling and struggling with the swik 'thing' (words fail me...),
but couldn't find it, I know it is somewhere...

Also any other feedback on what changes and improvements 9mount might
need before it can be made part of p9p (or maybe shipped with the
standard linux mount(1) tools?).
