* problem & solution
|
|
|
|
|
** unable to drop root
|
|
|
|
|
donot run under root
|
|
|
|
|
** in normal user, libseat permission deniened
|
|
|
|
|
add user in =video= group
|
|
|
|
|

|
|
|
|
|
** egl error

|
but it is copied using xoriso to =/iso/=
|
|
|
|
|
so I need to write a systemd service to automagically sync it at boot
|
|
|
|
|
** cleanup builds
|
|
|
|
|
=/nix/store/= takes too much space after build
|
|
|
|
|
#+BEGIN_SRC sh
|
|
|
|
|
unlink result
|
|
|
|
|
nix-store <path>
|
|
|
|
|
#+END_SRC
|
|
|
|
|
and there're a few tools for visualising disk size:
