opt can not be saved persistent

[crazy_jay]

Hi,

I'm very new to TinyCore. I'm using Ubuntu and want to try TC. So I installed TC to my existing Linux partition and add to grub boot loader :

                        linux /tce/boot/vmlinuz rw quite tce=sdb2 opt=sdb2 home=sdb6

where sdb2 is my ubuntu root partition and sdb6 my ubuntu home.

But the opt folder will be delete everytime I reboot. So I have to backup to get my configs persistent.  What am I doing wrong?

Many thanks!

Opt will not be deleted every time you boot.

Hi crazy_jay
You might want to mention which version of Tinycore you installed. You should be more specific
about the symptoms. Let me help you:
After I reboot
A. There is no /opt directory on my system.
B. My /opt directory is empty.
C. My /opt directory only contains the stock Tinycore files.
Please select the answer that best describes your problem, or elaborate using your own words.
I don't know if it is wise to map Tinycore directories to another Linux system. Possible permission
problems come to mind. For /home, user startup scripts may be incompatible.

Sorry, by "opt will be deleted" I mean the configurations ( bootlocal.sh) I saved in there during my session will be lost.
For example I configure my eth0 and saved. But every time I reboot, I have to do it again. The opt directory only contains the stock TC files. I'm using TinyCore Plus 4.2.1.

In the installation it says :

"If you already have a Linux System booting, then you do not need to make a partition for Tiny Core! Tiny Core can run in a single directory in your existing Linux installation."

So I guess it should not be a problem

Sounds to me like your sdb is not being found.
Add boot code "waitusb=5".

[crazy_jay]

But I don't want to boot from usb. TinyCore is already running from my sdb2. sdb6 also exists! I only have problem with the opt directory and don't know why

[gerald_clark]

When you use the opt= boot code, you must remove opt from .filetool.lst or restore may overwrite your files.

If not a usb then shouldn't the path be sda1 etc then?

Hi crazy_jay

"If you already have a Linux System booting, then you do not need to make a partition for Tiny Core! Tiny Core can run in a single directory in your existing Linux installation."

That refers to having a  /tce  directory for storing extensions and your backup file. The key phrase
there was "single directory". It says nothing about using a persistent  /opt  or  /home  in an existing
Linux installation. If you want to do that, I'd recommend you put those in their own partition.

coreplayer2: Not necessarily. If he has two internal drives, they could be mapped as sda and sdb.

If neither of the two "classical" issues mentioned in reply #4 and #6 are helping to resolve this, maybe it's time to share with us the output of: mount | grep /dev/sd

[crazy_jay]

The output for mount | grep /dev/sd is

/dev/sdb6 on /mnt/sdb6 type ext4 (rw,relatime,barrier=1,data=ordered)
/dev/sdb6 on /home type ext4 (rw,relatime,barrier=1,data=ordered)
/dev/sdb2 on /mnt/sdb2 type ext4 (rw,relatime,barrier=1,data=ordered)
/dev/sdb2 on /opt type ext4 (rw,relatime,barrier=1,data=ordered)

I remove the line opt from .filetools and change my bootlocal.sh a little bit. then I remove my backup so it wouldn't restore. So the solution from gerald_clark works!
But my Xorg configuration is lost. Do I have to use bootcode for etc too ? 
Or I just could move the TC directories to a new partition and let see if this problem is solved automatically.
Thanks you guys so much !!!

Do not forget to also remove home from .filetool.lst, as it is now on sdb6.

You need to add etc/X11/xorg.conf to .filetool.lst and do a backup.
