support/mkusers: allow comments in users tables

2015-10-18T15:52:21+00:00

The format of the users table files is non trivial, so it is sometimes handy to add comments explaining the syntax (or simply the reason for the user) inline in the files. Ignore empty lines and comment lines prefixed with '#' similar to shell or makedevs files. Packages that defined no user (the vast majority) would cause an empty line to be present in the internal users table, hence the reason we skipped empty usernames. Now that we ignore empty lines, we no longer need to check for empty usernames. Reported-by: Peter Korsgaard Signed-off-by: "Yann E.

scripts/mkusers: allow users with no password value set

2015-06-09T21:13:41+00:00

The following allows a user definition to specify that a created user entry should not have a password value set. Original implementation allowed a user definition to provide a password value of "=" (no quotes) to generate a crypt-encoded empty string value. In some cases, it may be desired to have no value specified for a user's password. By using a value "-" for a password, no value will be set in the shadow value. An example when this can be used is when logging into a terminal. Logging into a session with an encoded empty password will prompt a user to enter a password since it does not know the password is empty. If the password field blank, a login session will not prompt for a password. Signed-off-by: James Knight Acked-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

support/mkusers: enhance error messages

2015-03-29T11:39:25+00:00

The current error messages are a bit terse, and do not provide all the required information. Expand them to provide more context. Signed-off-by: "Yann E. MORIN" Cc: Tom Elliott Signed-off-by: Thomas Petazzoni

Change /bin/bash shebangs into /usr/bin/env bash

2014-10-24T23:55:37+00:00

Not all systems have /bin/bash (e.g. NixOS[1] doesn't). Buildroot already uses /usr/bin/env shebangs for other interpreters (perl, python), so why not bash? This changes only the shebangs used by Buildroot itself; stuff installed to the target system is left unchanged. With this applied I can run Buildroot unmodified on NixOS.

scripts/mkusers: allow the creation of groups alone

2014-10-22T19:39:12+00:00

Let mkusers create groups alone, useful for supplementary permissions in udev/systemd for example where users can be added to later at runtime. Use a magic string "-" to signal that user creation should be skipped. Signed-off-by: Gustavo Zacarias Acked-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

filesystems: also chown symlinks

2014-06-09T09:28:57+00:00

Currently, the symlinks in the generated filesystems will have the UID of the user running the build, because 'chown' does not change the ownership of symlinks, by default. Although the implications are limited, some may not want that UID to leak in the generated filesystems. So, use 'chown -h' so even symlinks get properly chowned.

support/mkusers: fix warnings when adding a new user

2014-04-05T16:39:16+00:00

When adding a new user (or a new group), we would get warnings, like: [...]/support/scripts/mkusers: line 145: [: too many arguments This is because we're checking if a UID (or a GID) is already defined, and/or is different from the requested one, both checks in the same test. Of course, if a UID (or a GID) is not defined, it does not have a value, so we can not compare it to an integer. Fix that by splitting the test in two, so the second is only executed if the first is sucessful. Reported-by: Thomas Petazzoni Signed-off-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

infra: replace BUILDROOT_CONFIG with BR2_CONFIG

2014-02-09T16:00:13+00:00

To make the naming consistent (all user-visible options should be prefixed with BR2_). An entry is added to Makefile.legacy to warn users who have set BUILDROOT_CONFIG but not BR2_CONFIG. Still export BUILDROOT_CONFIG but pointing to some phony value, to make sure that scripts that still use it fail in a predictable way.
