>Description:
tunefs -p won't work on a mounted filesystem.
Here's a patch that works for me
>How-To-Repeat:
# tunefs -p /usr
tunefs: cannot work on read-write mounted file system
#
>Fix:
There's a check at the moment to check that a filesystem is mounted
R/W. If it is, tunefs exits prematurely. We need to avoid bailing out
at this point, and instead open the raw device in readonly mode
(otherwise we won't be able to open the device file, 'cause its busy)
Patch for /usr/src/sbin/tunefs/tunefs.c included
(uuencoded to keep whitespace for my cut-and-paste-to-web-browser)
