was able to make it work by running the mkdir and cp commands by hand in kterm..
those 3 tiny buttons now have unclipped characters..

but something weird happening..

i had earlier followed some post here to change home from /tmp/root to /home/root

now running
Code:
echo $HOME
or
Code:
echo ~
still gives
Code:
/tmp/root
as the output..

but.. doing a
Code:
mntroot ro
or a
Code:
mntroot rw
is not affecting /tmp/root.. it's affecting /home/root..

so.. i did:
  1. Code:
    mntroot rw
  2. Code:
    mkdir -p /home/root/.config/galculator
  3. Code:
    cp /mnt/us/extensions/galculator/.config/galculator/galculator.conf /home/root/.config/galculator/galculator.conf

which works.. but should i leave root fs in rw mode..

would like our experts' explanation for above behaviour..

fsp on /mnt/us type fuse.fsp (rw,nosuid,nodev,noatime,user_id=0,group_id=0)
The answer to all your questions lies above, namely in what is mounted where. /tmp is just a symlink to /var/tmp, and /var is a tmpfs, so it will disappear after shutdown.

/home would be on the root partition, and thus read-only in normal use. And yes, I agree that it's a bad idea to leave root mounted rw for normal use.

You have two options here: use a home directory on the USB partition (/mnt/us), or in /var/local. The advantage of the former is that you can edit files via USB, the advantage of the latter is that it's a real filesystem, not FAT32. I suggest to go for /var/local/home/root, or /var/local/root, or whatever you please.

To have galculator config in /mnt/us/extensions/galculator/galculator.conf change galculator/usr/bin/run.sh to:
Code:
#!/bin/sh
GALCULATOR_CONFIG=/mnt/us/extensions/galculator/galculator.conf \
GTK_IM_MODULE=kindle \
GTK2_RC_FILES=/mnt/us/extensions/galculator/pixmaps/gtkrc \
/mnt/us/extensions/galculator/usr/bin/galculator

well.. baf seems to have found a simple solution..
but thanks to ixtab for explaining..
i need to fix my home location..
need to read and understand in detail..
am still puzzled by why echo $HOME and cp to ~ still recognise /tmp/root as home.. whereas mntroot and galculator itself consider /home/root..

@baf Excellent point. I forgot about that lol.

Yeah, I'm not sure why the HOME isn't being honoured either.

EDIT: Updated top post

Galculator uses g_get_home_dir() to get user's home dir and this function takes it from passwd file rather than from env variable.

As baf said. Your current shell instance still uses the old values. Logging out and back in should fix that.

Will fix.

i've done a restart more than once after doing the home location fiddle.. surely that should be enough..?

..and i go to the kindle CLI either through kterm or ssh.. in both, i come out by typing exit.. or in the case of kterm sometimes, by using the 2 finger menu>quit option.. don't these count as a "logout"..?

will check again..

Hmmm... I don't know. For me, it works as it should:

Code:
$ ssh root@kindle
[root@kindle root]# mntroot rw
system: I mntroot:def:Making root filesystem writeable
[root@kindle root]# grep ^root /etc/passwd 
root:x:0:0:root:/tmp/root:/bin/sh
[root@kindle root]# sed -i -e 's/\/tmp\/root/\/var\/tmp\/root/' /etc/passwd 
[root@kindle root]# grep ^root /etc/passwd 
root:x:0:0:root:/var/tmp/root:/bin/sh
[root@kindle root]# mntroot ro
system: I mntroot:def:Making root filesystem read-only
[root@kindle root]# echo $HOME
/tmp/root
[root@kindle root]# ^D
Connection to kindle closed.
$ ssh root@kindle
[root@kindle root]# echo $HOME
/var/tmp/root

there seems to be a difference between logging in through ssh and "logging in" through kterm.. see screenshots..
ssh recognises the "new" home at /home/root..
while the kterm session is still hung up on /tmp/root..
