Persistent USB
« on: October 26, 2009, 11:20:36 PM »
I have TinyCore installed to a flash drive and am able to boot from it.  Once booted, I can mount the local drives on the machine manually, but I need the drives to be mounted automatically. 

I have edited /etc/fstab and added in what I believed to be the necessary lines but when I restart the computer and boot again, the changes to fstab are not saved.

How do I make the changes stay or at least modify it enough to mount all drives in the system on boot.

If I was to mount a drive automatically, the easiest way would be to put "mount /dev/sda1" in /opt/bootlocal.sh and perform a backup so it would persist and run that command on next reboot.

I have my mount command in .profile since mount can be done form normal user.

Two questions on this method. 

1)  How would this work with an unknown computer?  Say it had 2 local drives or 2 paritions on the one drive.  Would it mount both or just the drive that is recognized as sda1

2)  You say perform a backup, how is this done?

Just mount via UUID. Then the drive can be mounted no matter what it is seen as on the computer.

mount -U uuid /mnt/somedir

I've noticed that while the usual mount command can be executed by the nomal user (for example tc), the above command must be run by root.
Any problem then with permissions in files/dirs?

No, it's the unix philosophy. An user can only mount what The Superuser has told he can, by creating the directory, giving permissions, and adding an fstab entry saying that he can.

edit:
Example fstab line, if this is desired:
Quote
LABEL=MyStick      /mnt/sdc1    auto   defaults,noauto,users  0     0
