Not needing "mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system"?

[lvlln]

In all the instructions that involve changing files under /system, I see that the first thing to do is to mount it as read-writeable, then at the end, mount it as read only:

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
...
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system

However, I'm finding that I can read-write files in the /system directory just fine without all the remounting. Does anyone know what this could mean? My phone seems to be functioning just fine so far. Should I try mounting /system as ro like in the last step just to be safe?

you need to use that command to write in /system/bin

you need to use that command to write in /system/bin

I see, so it's not for any subdirectory or file under /system, but only for editing/creating files/directories under the bin subdirectory?

EDIT:

I've attached a couple very simple scripts (just copy-pastes of the actual commands) you can put into the /system/xbin folder to simplify the process of mounting /system to be read-only and read-write. Remove the '.txt' before putting them on there.

Saves a lot of typing and removes potential for typos.

I am trying to mount my /system folder, and it appears to work how ever when i try to copy a file up with the "adb push" permission denied.

any idea why?

I must be running this command wrong somehow...
