Crazy (kernel?) ideas ...

• It pays to burn lots of CPU cycles to improve I/O

• • Desktop machines run only 1 task => no elevation etc.

• Filesystem metadata sizes:

• • 4Gb plain OpenSUSE Gnome install on sda1: 16Mb of .xml
  • • compressed (gzip): 2.6Mb => 0.065% - omits permissions, metadata etc. true: but these are perhaps highly compressible.
    • Assuming a linear scaling; 32Mb of memory would describe 50Gb of disk. linear scaling – better than linear expected (?) [ use a flash device ? ]
    • Why read a directory or inode ever again ?

• Transparent block re-mapping (eg. FSFS)

• Late block allocation, opensize ...

• Filesystem / layout hints for package install

• • • trylink / “watch me”; have a 'foo_magic_test_init' symbol(?)
    • Almost all systems install serially, help the FS do layout better ?
