I've made a small hack to prevent Kobo from importing dotfiles/folders. It uses LD_PRELOAD to override the directory syscalls and skip over dotfiles other than .kobo* and .adobe-digital-editions. It only applies to the nickel process. This hack was made to solve the issue mentioned in
the firmware thread.
This will survive through firmware upgrades. To remove it, you'll need to wait until I make a script for that, or you can delete /etc/ld.so.preload and /usr/local/geek1011/libhidedir_kobo.so (you can also factory reset). I've done some preliminary tests, and everything seems to work well.
See here for the code and more details:

Update for 4.17.13694+: There's now a official config option which can do basically the same thing. If you want, you can still use this hack (it will still work). See near the end of this thread for how to use the config option. The disadvantage of the config option is that it won't persist after a sign out and that it will delete stuff if you don't get it right the first time, but otherwise, after the initial setup, they're pretty much identical.
