I'm talking not about plugins or architecture, but about ability of
remount current aufs branch with appending another one layer. Why it
should not be possible?
I can refresh menu indexies by myself after mounting.
For example - If I boot without persistence partition, I have some
limited part of RAM for my changes. So, if I install libreoffice or
some other big application, the size of available ram is decreased. But
I need LO not so often to save it to persistent or include it to the
squash, because from time to time I use boot to ram option.
I want to use advantage of AUFS, that allow me fast connect or
disconnect some fuctionality.
Live-example of using:
1 Insert usb-flash into port of netbook, booting to ram
2 Using this flash for making something on neighbour computer, while
working on first
3 I need to open some document on first, so I plugging usb-flash
back to the first computer, plug needed sfs with software, working
with document (for example libre office or freecad), unplugging aufs
layer and again disconnect flash.
It makes me free to combine modules for my needs at the moment.
Something like this was realised in puppy linux and it's really very
comfortable to use.
All of I need - is right syntax and branch name for remount aufs on /.
