Filesystem Layout
This is the first file system hierarchy, used by qLinux 0.1!
Top-Level Directories
| /apps | unused right now | ||
| /data | non-executable data which does not belong to a package (not data usually under “share”) | ||
| /exec | a pool for executables which are not in the PATH, single binaries/scripts, symlinks for apps/misc/plng executables | ||
| /home | home directories of users and services which requires a dedicated user(s) and home diectory | ||
| /libs | libraries not relevant to the OS, usually shared libs | ||
| /misc | software which doesn't match to a category, small packages | ||
| /mntp | mount points, the real mountpoints shall be sub directories | ||
| /plng | programming languages (perl, python) | ||
| /qlnx | the OS itself | ||
| /xsys | the X windows system |
The directories /qlnx , /plng , /misc and /libs are considered as main categories.
Second Level Directories
Subdirectories of Category Directories
| bin | all executables (incl. “sbin” files) for packages in this top-level directory | ||
| dat | partially replacement of /usr/share from packages in this top-level directory |
||
| etc | config files from packages in this top-level directory | ||
| inc | header files from packages in this top-level directory | ||
| lib | libraries from packages in this top-level directory | ||
| man | man pages from packages in this top-level directory |
Subdirectories of the OS (only)
This is the operating system directory. It shall contain OS related software/packages only.
| dev | linux kernel (tmpfs) | ||
| log | all logfiles1) | ||
| prc | linux kernel (tmpfs) | ||
| run | linux kernel (tmpfs) | ||
| sys | linux kernel (tmpfs) | ||
| var | variable data exclude directories log, run and tnp, reduced number of subdirectories and levels | ||
| | |
Eliminated Directories
| /boot | moved to /qlnx/etc/boot |
||
| /etc | splitted to etc per top-level directory |
||
| /home | see below | ||
| /root | moved to /home/admin (see below) |
||
| /sbin | files (admin executables) are now in /qlnx/bin with mode 0754 |
||
| /usr | removed without direct substitution | ||
| /usr/share | commonly moved to dat for data, otherwise depending on type of file(s), depends on category always |
||
| /usr/local | n/a without direct substitution | ||
| /usr/libexec | moved to bin/libexec depending on category |
||
| /var | partially moved to /qlnx/var , some former folders are directly under /qlnx now |
Over Directories
The "/home Directory
The /home directory contains 3 sub directories:
/home/admin | the home directory of the root user | ||
/home/srvcs | directories of services/daemons which requires a dedicated user and are not part of the core of qLinux | ||
/home/users | home directories for ordinary users (similar to the traditional /home ) |
| /etc/default | not defined yet | ||
| /libs/etc/ssl/certs | the central directory for certs |
