# Logging in as a user in wheel gives
#   'Failed to set ACL on /var/log/journal/...: Operation not supported'.
# 
# `getfactl` shows incorrect permissions for `/var/log/journal`.
#
# Setting permissions manually with `setfacl` returns 'Operation not supported'.
#
# `tune2fs -l /dev/mmcblk1p2` shows 'user_xattr acl'.
#
# `# CONFIG_EXT4_FS_POSIX_ACL is not set` found in
#   https://github.com/archlinuxarm/PKGBUILDs/blob/master/core/linux-veyron/config
#
# Trying mainline kernel gives a white screen on boot.
#
# Performing `makepkg -s` for linux-veyron with `CONFIG_EXT4_FS_POSIX_ACL=y` fails with
#   'error POSIX_ACL not supported in 3.18 backport'.
#
# Per https://issuetracker.google.com/issues/37055401, ACLs are insecure until 3.18.
#
# Modifying linux-veyron package for ChromeOS-3.18 fails with 'CONFIG_SND_PROC_FS=y'.
# Found patch at https://patchwork.kernel.org/patch/6505191/

# make[1]: *** [scripts/Makefile.build:402: drivers/staging] Error 2

#
# Made patch for undeclared 'BRCM_CC_43430_CHIP_ID', 'BRCM_CC_4345_CHIP_ID',
#   and 'BRCM_CC_4358_CHIP_ID' defines.
#
# Added patch from https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1424676
#
# Made more patches.
#
# "Couldn't open 'arch/arm/boot/dts/rk3288-brain-rev0.dtb': No such file..."
# Brain was an experimental Rockchip Veyron board. C201 uses Veyron Speedy.
# Linux master has dts for Speedy.
# Learned to compile dts to dtb: http://elinux.org/Device_Tree_Reference
# Learned about the dtb compile process for Linux:
#   https://groups.google.com/forum/m/#!topic/beagleboard/FF0bxl-uDfo
# Added missing dtsi dependencies from Linux master.
# Tracking down missing defines.
# `make dtbs` finally succeeds. Rerunning `MAKEFLAGS=-j4 makepkg -s`.
#
# Cleaning up patches.
# Struggling against `git apply`.
# Changing to `patch` to avoid dumb git complications.
# Rerunning `makepkg -s` for sanity before pushing to fork.
#
# Pushed to fork: https://github.com/jonnystorm/PKGBUILDs/tree/linux-veyron-3.18/core/linux-veyron
#
# Installed new kernel and headers. Rewarded with a black screen at boot.
#
# Reintegrating patches from linux-veryon-3.14 package.
# Rebuilsing.
# Boot to black.
#
# Reviewing differences between new dts and `rk3288-brain-rev0.dts`.
# Building with `rk3288-brain-rev0.dts` and supporting files.
# Black screen.
#
# Said fuck it and went back to ChromeOS 3.14 without ACL support.
# Installed suckless.org everything. All is well.
#
# `wlan0` disappears on suspend/resume.
# Found fix at https://wiki.debian.org/InstallingDebianOn/Asus/C201#WiFi
