Manage Union FS...

Can you replace UNIONFS to point to a hard disk instead of the RAM DISK?

In that way, i guess all changes can be restored at boot time right? if so how can changes be restored?

thanks

Cheatcode unionrw works (reasonably well) in Kanotix. I have a folder sda1/union so I use the cheatcode
unionrw=/mnt/sda1/union

Not all things are 'unionable'; I don't know if this works in Knoppix though.

Does NOT work with Knoppix 4.0.2 unfortunately. Looks like a pretty necessary feature, as ramdisk is very limited size wise and volatile (i.e. does not survive a reboot) with regards to retaining the programs installed.

You need to write a new folder called union on your pen drive / hard drive first. Then call unionrw=etc. If you've already done that . . . try kanotix?

knoppix 4.0.2 already support unionfs mount not only ramdisk, but the whole system l guess.
I previously answer the simiar question at there:

I don't believe that's the case. unionrw allows union directories / files to be retained in a future reboot otherwise the LiveCD files will start each time. unionrw manages apt-get update and (software) install at future reboots.
