X-Git-Url: https://git.rkrishnan.org/?a=commitdiff_plain;h=5995d11a3c320bd55d76eb2815832c6bfaacf475;p=tahoe-lafs%2Ftahoe-lafs.git

remove automatic private dir
 * rename my_private_dir.cap to root_dir.cap
 * move it into the private subdir
 * change the cmdline argument "--root-uri=[private]" to "--dir-uri=[root]"

-my_private_dir.cap (optional): When you create a new tahoe client, this
-file is created with no contents (as an empty file).  When the node starts
-up, it will inspect this file.  If the file doesn't exist then nothing will
-be done.  If the file exists, then the node will try to read the contents of
-the file and parse the contents as a read-write URI to a mutable directory.
-If the file exists but doesn't contain a well-formed read-write URI to a
-mutable directory (which is the case if the file is empty), then the node
-will create a new decentralized mutable directory and write its URI into this
-file.  The start.html page will contain a URL pointing to this directory if
-it exists.
+root_dir.cap (optional): The command-line tools will read a directory cap out of
+this file and use it, if you don't specify a '--dir-uri' option or if you
+specify '--dir-uri=root'.
