From 6763df16f143667eaa21cbaa987dc98135bdd7f5 Mon Sep 17 00:00:00 2001 From: robk-tahoe Date: Thu, 25 Sep 2008 06:47:30 -0700 Subject: [PATCH] fuse/impl_c: UNDO --auto-fsid option rolling back: Thu Sep 25 14:42:23 BST 2008 robk-tahoe@allmydata.com * fuse/impl_c: add --auto-fsid option this was inspired by reading the fuse docs and discovering the 'fsid' option to fuse_main, and was _intended_ to support a sort of 'stability' to the filesystem (specifically derived from the root-uri mounted, whether directly or via an alias) to support mac aliases across unmount/remount etc. some experimentation shows that that doesn't actually work, and that, at least for mac aliases in my testing, they're tied to path-to-mountpoint and not to the fsid - which seems to have no bearing. perhaps the 'local' flag is causing weirdness therein. at any rate, I'm recording it simply for posterity, in case it turns out to be useful after all somewhere down the road.
