+Do not run the build system on a eCryptfs file system, because it has
+very short file name limits and Libreboot's build system deals with very
+long file names. We commonly get reports from this by Linux Mint users
+who encrypt their home directory with cryptfs; use a serious distro like
+Debian or Arch please. And use a decent file system; zfs or perhaps mdcrypt
+with btrfs will do nicely.
