acngfs - Virtual file system for use with apt-cacher-ng
acngfs BaseURL ProxyHost MountPoint [ -o FUSE Mount Options ]
acngfs is a FUSE based filesystem which represents files downloadable via HTTP as part of a local filesystem. It has been developed for very specific purposes and is not intended to be a general purpose HTTP filesystem.
The main use case for acngfs is a situation where:
Typical use may be to let apt/dpkg use package file like they are present on the local filesystem so there is no need to download them. In sources.list, the source appears as a file:/ type URL, like:
deb file:/var/local/acngfs_debian unstable main contrib
and the filesystem backend is prepared with a command like:
/usr/lib/apt-cacher-ng/acngfs http://ftp.uni-kl.de/debian localhost:3142 /var/local/acngfs_debian -o allow_root
The command-line options supported by acngfs are:
Permissions of the files are important when using mounting when sharing data with other users (including root!). To mount as user and let root use the package management tools (apt, dpkg), one may need to use FUSE options like in the following example:
acngfs http://ftp.uni-kl.de/debian http://localhost:3142 /mnt/misc -o allow_root
See FUSE documentation for details about file permissions representation.
Software is still experimental, use at your own risk!
There are natural limitations on capabilities of the FS: no directory reading is allowed (only descending), permissions of files are inherited from the mount point as well as other properties of the filesystem.
Should be used with apt-cacher-ng version 0.2pre2 or newer; otherwise it will flood log files with many requests of small file chunks.
