Do not put anything here. This is a clean zone. It is
the root filesystem. |
| /bin |
Y |
N |
N |
OS specific, vendor-supplied filesystem where general-use
binaries that have to be there when the only the root filesystem
lives live. We should only add globally approved binaries listed in Appendix A to this directory. |
| /etc |
N |
N |
N |
System configuration files. This is the only part
of / that should do much changing, and even this filesystem should
only be changed after severe consideration. |
| /etc/init.d |
N |
N |
N |
All rc files live here and get linked to from
the /etc/rc.d/rc#.d directory. Some versions of Linux have
an /etc/rc.d/init.d. This should be linked to /etc/init.d for
standardization. |
| /etc/packagename |
N |
N |
N |
Home for package-specific (ntp, amd, samba,
etc) configuration files.
|
| /home |
N |
N |
N |
Local disk which provides user's home directory. No path
should ever point here, except for the /u link maintained by
amd(8). Do not reference this directory in any scripts. |
| /lib |
Y |
N |
N |
OS specific, vendor-supplied filesystem where general-use
libraries live. We don't mess with this filesystem.
|
| /man |
Y |
N |
N |
OS specific, vendor-supplied filesystem where manpages
live. We don't mess with this filesystem.
|
| /n |
N |
A |
N/A |
Host space. Used to access any filesystem exported by
any host. /n is controlled via an amd(8) map.
|
| /opt |
Y |
N |
N/A |
EVIL. Some vendors insist on installing stuff
in /opt. This is an evil Sun-ism and should be resisted if
at all possible. Create it only if there is no alternative. Document
that it was created and why. |
| /sbin |
Y |
N |
N |
OS specific, vendor-supplied filesystem where sadmin
binaries live. We should only add globally approved binaries listed
in Appendix B to this directory. |

Y |
Deprecated. Replaced by /usr/nikola. Remove from
user's paths. Do not add anything new to it.

N |
A |
N/A |
User home directory mapping space.
/u is controlled via an amd(8) map.

N |
N |
Basic root location for system binaries. Don't
mess with it. |
| /usr/bin |
Y |

binaries live. We should only add globally approved binaries listed in Appendix C to this directory. |
| /usr/lib |

libraries live. We should only add globally approved binaries listed in Appendix D to this directory. |
| /usr/local |
N |
N |
Y |
Basic root location for local-to-the-host required
binaries. This is a small space, so don't put too much stuff in it,
just things that must be here. |

Our locally-mounted user-realm binaries live here. |

we put this host's specific daemons that must be present on boot.

This is where varable files go. This includes spool files
