Hello, all. While testing on raspberry pi using standalone image I've
noticed that all file operations were sluggish. The culprit was tar that
we use as a filesystem for memdisk which requires complete scan to find
one file. On most systems it's a minor time penalty but on raspberry pi
it almost halved boot time. I propose a specialised compact and fast
uncompressed read-only filesystem by storing filenames in sorted array
and using binary search. It's a pretty big change but I feel like it's
worth to be put into 2.02.
Does anybody disagree?
