Persistent DoUSB is based on ext4 install ? Delayed write to USB drive

Many aspired to make Austrumi liveUSB drive same as hdaxinstall.

Livecd is Dolivecd. LiveUSB is DoUSB. Just to get all the software run in the dram, then support it with cdrom/cdrw or uSB drive.

To make it persistent, livecd needs to write to cdr or cdrw with track at once or multisession capability. To make it persistent on USB drive, ext4 can do delayed write from dram to USB drive ext4 file system. It can also save the session by ext4 file system on shutdown command.

Austrumi if using the latest kernels will automatically doUSB and have ext4 to be persistent.

Just have to watch out for writebacks and have local defragmentation if writebacks exceeded number 6 to defrag immediately by a write thru. This is done by Drupal in the old days. Now you have to make sure your ext4 has the local defrag module.

Persistance USB install, just means that you save the config files before you shut down. You have to save first, then after you reboot, the config is upto date.
