system: allow selecting merged /usr along with custom rootfs skeleton

2019-02-06T16:11:38+00:00

If the user is brave enough to use a custom rootfs skeleton then we must not prevent using merged /usr too. Actually it is already possible to do this, although indirectly, by selecting BR2_INIT_SYSTEMD. Signed-off-by: Carlos Santos Signed-off-by: Arnout Vandecappelle (Essensium/Mind)

skeleton: use BR2_SYSTEM_DEFAULT_PATH as default PATH

2018-12-31T13:32:44+00:00

We substitute the path specified in system/skeleton/etc/profile with the path specified in the configuration variable $(BR2_SYSTEM_DEFAULT_PATH). $(BR2_SYSTEM_DEFAULT_PATH) is a Kconfig string, so it is already double quoted. This means that export PATH=value will now be export PATH="value" in /etc/profile, which is perfectly fine. Signed-off-by: Markus Mayer Reviewed-by: "Yann E.

system: introduce BR2_SYSTEM_DEFAULT_PATH option

2018-12-31T13:32:20+00:00

The configuration option BR2_SYSTEM_DEFAULT_PATH allows the user to override the default path, which can be used by /etc/profile and some system daemons. It defaults to the value previously hard-coded in /etc/profile. This default should be suitable for most users. Signed-off-by: Markus Mayer Reviewed-by: "Yann E.

system cfg: remove mkpasswd MD5 format option

2018-12-15T10:33:29+00:00

As SHA256 is now default, removing weak MD5 option. C libraries now all support the SHA methods. glibc 2.7+ uclibc (bdd8362a88 package/uclibc: defconfig: enable sha-256...) musl 1.1.14+ One issue this would prevent, is a host tool issue with a FIPS enabled system where weak ciphers/methods are disabled. It seems the crypt(3) call is impacted by /proc/sys/crypto/fips_enabled (per crypt(3) man page). It results in mkpasswd returning "(EPERM) crypt failed." Rather then create a Buildroot host dependency check, this patch removes the potential corner case from being selected. Acked-by: "Yann E. MORIN" Cc: "Yann E.

system cfg: set mkpasswd default to SHA256

2018-12-15T10:26:37+00:00

This patch changes the default mkpasswd method to SHA256 from MD5. The change both improves the quality of the hash used and prepares for eventually removing MD5 as a option. Reviewed-by: "Yann E. MORIN" Signed-off-by: Matthew Weber Signed-off-by: Peter Korsgaard

package/systemd: needs glibc

2018-11-22T16:15:33+00:00

Since version v239, systemd-nspawn unconditioanlly uses prlimit(2), which is not implemented in uClibc-ng. systemd-nspawn can not be disabled. This makes systemd glibc-only again. After a bit of discussion with upstream (om IRC), it looks very improbable that they accept a patch making systemd-nspawn optional. They would probably consider a patch that provides that syscall wrapper if it is missing, though, but that's less trivial... Signed-off-by: "Yann E.

system: update Config.in comment about systemd dependencies

2018-09-14T22:05:48+00:00

In commit 879fa7f82a86ffdc6d1cf7c9bfbb5cf830583d69, the BR2_INIT_SYSTEMD option was changed to allow selecting with a uClibc toolchain. Unfortunately, the corresponding Config.in comment, which was already bogus, was not updated to take into account the numerous dependencies of BR2_INIT_SYSTEMD. Due to this, even if you have uClibc enabled, the BR2_INIT_SYSTEMD option may not be visible, and the Config.in comment may also not be visible, leaving the user in the dark. This commit fixes the dependencies of the Config.in comment so that they match the one of the BR2_INIT_SYSTEMD option. Reported-by: Raphael Jacob Cc: Raphael Jacob Signed-off-by: Thomas Petazzoni

skeleton: PAGER without blank and unset at end of for loop

2018-06-05T16:50:49+00:00

The PAGER environment variable is including a blank character at the end. Remove this. A for loop has been unsetting the variable inside the loop, this is only needed once at the end of the loop. Signed-off-by: Florian La Roche Signed-off-by: Thomas Petazzoni

skeleton: add /dev/fd, /dev/std{in, out, err} symlinks for static /dev on readonly rootfs

2018-05-01T19:53:45+00:00

Some applications, e.g. bashs process subsitution feature, rely on the convention of `/dev/fd` being a symbolic link to `/proc/self/fd`. When a static /dev is used on a readonly rootfs then the runtime ln invocations in the inittab will fail, so we need to add the symlinks at build time. Makedevs doesn't support creating symlinks, so instead add the symlinks to the default skeleton. For non-static /dev setups, the kernel will mount devtmpfs which shadows the /dev of the rootfs, but then the runtime ln invocations in inittab will create the symlinks. Signed-off-by: Peter Korsgaard
