Version: 2.0.873+git0.3b4b4500-2
Severity: important

Dear Ritesh and Turbo,

this new patch is causing trouble for two reasons. Here are the relevant lines from patch 7e1ae42:

+	    while read fs; do
+		set -- $(eval echo "$fs" | sed 's@:@ @')
+		case "$1" in
+		    swap)
+			swapon $2
+			;;
+		    *)
+			fsck -a "$2"
+			if mount "$2" >/dev/null 2>&1; then
+			    MOUNT_RESULT=0                   <----- this does NOT change the value for the last line
+			    break                            <----- this is the break line I removed
+			fi
+			;;
+		esac
+	    done

       log_end_msg $MOUNT_RESULT                             <----- this will stay on 1 from inital setting

1) The “break" is exiting the while loop after mounting the first found target disk successfully, ignoring all further disks which might still be in the loop value list. I fixed this behaviour for myself by just removing the break line. This should be the correct fix.
2) "MOUNT_RESULT=0" is NOT changing the value to 0 because MOUNT_RESULT was initially set to 1 outside the nested loops/pipes. So the function/script will always call log_end_msg with the initial value of 1, displaying a “failed” after the init script finishes. I fixed this for myself by just explicitely setting the value of MOUNT_RESULT to 0 before the log_end_msg line. Of course, this is not representing the correct result of the mount calls - but currently it is not doing that as well. This is only a workaround.

Best regards,
