As bootes, I can do: # /usr/glenda/bin/rc/pullbut typically get something like: error: copying /n/boot/sys/src/9/pc/sdata.c: '/tmp/replica00000651' permission denied
I think you could just start ramfs(4) before you pull, or otherwise get a writable /tmp in bootes' namespace, to prevent the error above.
You can use wstat (in fossilcons(8)) to change uid on files. -Josh
