Problem with home directory

[guillaumetld]

Hi, i have some problems with my home directory.

In fact, i would like to edit .jwmrc file. I can open it, but the problem is that i can't save the modification i make, even with root. It's said that it's a read only file, but even with chmod 777 it doesn't work.
Moreover i saw that if i save a file in /home it's deleted at the next reboot, even with home=hda1 in extlinux.conf

Sounds like /dev/hda1 is not being mounted on /home.
What does mount show?

... Moreover i saw that if i save a file in /home it's deleted at the next reboot, even with home=hda1 in extlinux.conf

That indicated in my view that 'home' is still included in '/opt/.filetool.lst' and hence the restoration from backup and your persistent home (on 'hda1') are "fighting" with each other over those files. The need to exclude persistent directories from backup has come up now countless times in the forum and is clearly explained in the wiki.

On this point I wonder whether this needs to be highlighted more strongly (in RED and 24 pt font ??) in the wiki, or better added to the FAQ, as it pops up so often.

The problem with the '.jwmrc' file sounds like what would happen if the file is not a file but a symbolic link into an extension. Running ls -al .jwmrc should clarify this quite easily.

[guillaumetld]

but home is NOT indicated in filetool.lst and i am sure of that.

Nevertheless, you are right with the fact that .jwmrc are symbolic links. The real file is in tmp/tcloop/jwm/etc/skel
and i can't remove them, even in root.

edit: At boot, i have chmod: /home/tc/.jwmrc: Read only file system
edit 2: If you have a solution, it's good for my knwoledge, but i installed jwm snapshot and it works perfectly.

edit 3: Just an other question. I would like to modify the /usr/local/tce.jwn and launch a program called bclient.bat, located in /home/shop.
I tried to use exec /home/shop/bclient.bat but it doesn't work, because bclient.bat call other files with relative links, and i don't want to modify all the code...In fact, i always need to cd /home/shop before launching this program. Then, i tried to use cd /home/shop in my tcejwm, but it doesn't work. Any idea ?

If you are talking about the .jwmrc links to /tmp/tcloop/jwm in your home directory then to correct this try the following:

cp -L /etc/skel/.jwmrc* .

Answer y to overwrite each file. Both jwm and jwm-snapshot extensions need some adjustments.

Hi guillaumetld
Lets do a quick sanity check as to why you are losing your files in home. Post the output from:
sudo find / -iname mydata*
cat /proc/cmdline
cat /opt/.backup_device
cat /opt/.tce_dir

        [EDIT]: Added missing period in last line

[guillaumetld]

In the good order:

/mnt/hda1/tce/mydata.tgz
/etc/sysconfig/mydata

initrd=/boot/tinycore.gz quiet home=hda1 tce=hda1 opt=hda1 BOOT_IMAGE=/boot/bzImage

hda1/tce

cat: can't open '/opt/tce_dir': No such file or directory

I made a sudo find / -name tce_dir and there is nothing.

If you are talking about the .jwmrc links to /tmp/tcloop/jwm in your home directory then to correct this try the following:

cp -L /etc/skel/.jwmrc* .

Verifying the issue with .jwmrc files being read-only filesystem caused by linking to /tmp/tcloop, I have updated both jwm.tcz and jwm-snapshot.tcz. Not being a use of this window manager, I would appreciate feedback in the TCE section: http://forum.tinycorelinux.net/index.php/topic,11295.msg59308.html#msg59308

Hi guillaumetld
My fault, I didn't hit the . key hard enough, it should have read:
cat /opt/.tce_dir

That  /etc/sysconfig/mydata  entry looks a little suspicious, how are you running your back up?
Command line or using the GUI? If command line, what command are you giving? If GUI, is the
device listed as hda1/tce?

[guillaumetld]

/mnt/hda1/tce

I run my backup with the GUI, and i used the default option i had the first time which was hda1/tce.

[guillaumetld]

In fact, i overwrited the .jwmrc* in my /home, with the /etc/skel/.jwmrc* and it works now.

Nevertheless, i dont need to use jwm. The onliest thing i need is a desktop manager because i need to configure the right click, and see a bar with the windows openned. If you know a better one, i'm in !

Hi guillaumetld
I'm running out of ideas here. If you rename that  /etc/sysconfig/mydata  file to  /etc/sysconfig/nmydata
and run your back up and reboot, do you still lose /home files? Does  /etc/sysconfig/mydata show
up again?

Did you actually save a file to /home or a link to a file? Does anyone know if links get included in
back ups?

[guillaumetld]

It's working now in fact, maybe i fixed an error when i tried to do something else (in fact, i had some backup conflict before, maybe it's this ?).

[Rich]

Hi guillaumetld
Did you rename the file as I suggested? If so, if you change it back do your back up problems return?
