- Frequently Asked Questions about base-files
- ===========================================
-
- * Questions about "profile.d":
-
- Q. Why does Debian not have a "profile.d" directory, like other distributions?
-
- A. Because no Debian package needs it. Debian policy says: "A program
- must not depend on environment variables to get reasonable defaults".
- This policy has been very successful so far. If the default install
- had a profile.d, people might think it's ok to use it for a Debian
- package, when in fact policy does not support such thing.
-
- Q. Ok, but I still think it would still be a nice thing to have, would
- not make sense to have a profile.d by default, even if no Debian
- package uses it?
-
- A. No. As explained before, there is the risk of assuming that it's
- "officially supported". If you need a profile.d directory, you may
- still create one in your machine and modify your /etc/profile
- accordingly to enable it. Since this is a configuration file,
- its contents will be preserved in upgrades.
-
- Q. Ok, but if I do that I will have to merge my changes every time
- the /etc/profile provided by base-files changes.
-
- A. That should not be a big problem. The default /etc/profile provided
- by base-files is quite minimal on purpose, and it is not expected to
- change drastically from one Debian release to the next one.
-
-
- * Questions about /etc/issue and /etc/debian_version:
-
- Q. I upgraded my system to the testing distribution and now my /etc/issue
- says "squeeze/sid". Should it not read "squeeze" or "testing"?
-
- Q. I upgraded my system to the unstable distribution and now my /etc/issue
- says "squeeze/sid". Should it not read "sid" or "unstable"?
-
- A. You obviously do not understand how the testing distribution works.
- Packages uploaded for unstable reach testing after ten days, provided
- they are built for every released architecture, have no RC-bugs and
- their dependencies may be met in testing. You should consider the
- testing and unstable distributions as two sides of the same coin.
- Since the base-files package in testing was initially uploaded for
- unstable, the only sensible /etc/issue to have is one that is both
- valid for testing and unstable, hence "squeeze/sid" (or whatever is
- appropriate).
-
- Q. Why "squeeze/sid" and not "testing/unstable" as usual?
-
- A. The codename is a little bit more informative, as the meaning of
- "testing" changes over time.
-
- Q. Ok, but how do I know which distribution I'm running?
-
- A. If you are running testing or unstable, then /etc/debian_version is
- not a reliable way to know that anymore. Looking at the contents of
- your /etc/apt/sources.list file is probably a much better way.
-
-
- * Other questions:
-
- Q. Why isn't license "foo" included in common-licenses?
-
- A. I delegate such decisions to the policy group. If you want to
- propose a new license you should make a policy proposal to modify the
- paragraph in policy saying "Packages distributed under the UCB BSD
- license, Artistic license, GNU GPL and GNU LGPL should refer to the
- files in /usr/share/common-licenses". The way of doing this is
- explained in the debian-policy package. As usual, you should always
- take a look at already reported bugs against debian-policy before
- submitting a new one.
-
- Q. I upgraded from woody to sarge. Should my system be FHS-compliant now?
-
- A. Achieving FHS compliance by upgrading would be tricky and prone to
- error in certain cases, so it is not a goal of base-files, nor it is
- planned to be. By default, some "mandatory" directories (like /opt,
- /srv or /media) are only created in the first install (performed by
- debootstrap), to keep the code as simple as possible, follow the
- principle of least surprise on upgrades, and also to give people the
- freedom to remove those directories without them being created again
- when base-files is upgraded. Therefore, if you are running any sort of
- compliance tests, you should do it on newly installed systems only.
