File sizes and record dates are displayed in search results. The database can be categorized. The maximum file size allowed can be specified.
AVFS (A Virtual File System) is an easy-to-install system that enables all programs to access archived, compressed, remote, or other kind of virtual files without the need to recompile programs or the kernel. The following modules are currently implemented: tar, zip, rar, gzip, bzip2, ftp, http, dav, rsh/ssh, floppy, and many more.
ABISS (Active Block I/O Scheduling System) is an extension for the Linux kernel that implements priorities for disk IO operations, and that provides a means for applications to use these priorities to obtain real-time (e.g. a guaranteed data rate) and prioritized best-effort services. The kernel code is supported by a user space daemon and a library.
Autodir is a tool for creating directories transparently to the applications accessing them based on information available from sources like password and group databases. It currently supports the creation of home and group directories for LDAP, NIS, and SQL Unix accounts, and uses the autofs Linux kernel module to detect directory requests. It also supports calling backup programs when specific directories are not in use so that systems need not be taken offline for backup purposes.
