Description:        booting problem
Details:

after changing sysctl.conf values and rebooting (i ve used values in readme
file), my permissions changed and now i cant get into my ~/Library folder
and all my settings for applications, my mail, other things which is saved
in this folder - gone (not accessible)! when i rebooted again, nothing new
happened. it is very frustrating that your simple installation steps can be
so dangerous. what do i have to do now? fuck.
