AppFS

It's sort of like LazyFS.

Usage

Run: 1. # mkdir /tmp/appfs-cache /opt/appfs 2. # appfsd /opt/appfs

Paths

AppFS should normally be mounted on "/opt/appfs".

/opt/appfs/hostname
	Fetches: http://hostname/appfs/index
	Contains CSV file: hash,hashMethod,<certificateInDERFormatInHex>,<PKCS#1v1.5-signature-inDERFormatInHex>
                   \-------------/
                              ^- Signed data
	Fetches: http://hostname/appfs/<hashMethod>/<hash>
	Contains CSV file: package,version,os,cpuArch,packageManifestHash,isLatest

/opt/appfs/hostname/package/os-cpuArch/version
/opt/appfs/hostname/<hashMethod>/
	Fetches: http://hostname/appfs/<hashMethod>/<packageManifestHash>
	Contains CSV file:
		type,time,extraData,name
		type == directory; extraData = (null)
		type == symlink; extraData = source
		type == file; extraData = size,perms,fileHash

/opt/appfs/hostname/{packageManifestHash,package/os-cpuArch/version}/file
	Fetches: http://hostname/appfs/<hashMethod>/<fileHash>

Database

sites(hostname, hashMethod, lastUpdate, ttl)
packages(hostname, packageManifestHash, package, version, os, cpuArch, isLatest, haveManifest)
files(packageManifestHash, type, time, source, size, perms, fileHash, file_name, file_directory)
