Small issue with overlayfs

jannl · Post by **jannl** » Saturday 20 August 2016 15:58

I just activated the overlayfs with the wiki, everthing looks to work great.

When I issue a 'service saveoverlays sync', everything seems to go ok, however I get an error near the end of the script: '/etc/init.d/saveoverlays: 107: [: rw: unexpected operator'
Line 107 looks ok, so not sure what to do here.

Any clues?

Long time sine, but I think i fixed that. Please try downloading the service script again. Alternatively, try:
sudo bash -x /etc/init.d/saveoverlays sync
.... to debug more detailed.

thx, will try that later this week.

I downloaded the saveoverlays last saturday.
When I look at the file now, I see a space between #! and /bin/sh, which shouldn't be there I think (shebang line)

Furthermore, this should indicate /bin/sh is used instead of bash.

I will come back to this.

Issuing the command directly does not seem to give the error.

What presents the error is:

Code: Select all

sudo su -
mount -o remount,rw /
/etc/init.d/saveoverlays sync
mount -o remount,ro /

Error is in the saveoverlays

fixed by :

Code: Select all

-#!/bin/sh
+#/bin/bash

Have nice day

If that is the exact change, the line #/bin/bash does not do anything, because it is commented out.
