Subject: Root emacs weirdness
Date: 21 Sep 2013 11:22:06 GMT [thread overview]
Message-ID: <slrnl3r0gq.2n3.notbob@nbleet.hcc.net> (raw)
While learning about linux gutz, I used emacs dired by root to edit
/proc/sys/kernel/dmesg_restrict file from a 1 to a 0. Opened emacs /
from root, then went to said dir and edited file. Upon trying to edit
file using e, I get this in the mini-buffer:
Buffer is read-only: #<buffer dmesg_restrict>
.....but, I was then able to edit the file, nonetheless. ??? File
permissions are 644. When it came time to save the dmesg_restrict
file using C-x C-s, I get:
Cannot modify backup file ....something or other.....
IO error writing /proc/sys/kernel/dmesg_restrict: Invalid argument
.....and then do C-x k, I get the std 'still wanna kill buffer'
question (y). Yet, in the end, the file is modified. Also, jumping
up to the parent dir (/proc/sys/kernel), I see no back-up file (foo~)
is created. I tried this 4-5 times, trying to get the first part of
the above error msg and on the 5 try, it DID indicate the file has
been saved (wrote). !?!?
What the heck is --or is not-- going on??
I'm using emacs 23.3.1 on Slackware 13.37.
