fs: add missing $$(sep) to pre- and post-command hooks code

2017-11-05T16:52:27+00:00

When multiple hooks are registred, both pre-a and post-command hooks' foreach loops need to have a separator at the end in order for the code to work as intended. Without the separator all hooks end up as a one single line command thus making all but the first hook into no-ops. Fixes: 4628b6f3b4 ("fs: add pre- and post-command hooks") Cc: Yann E.

fs: add pre- and post-command hooks

2017-08-02T18:58:27+00:00

In some cases, the directory structure we want in the filesystem is not exactly what we have in target/ For example, when systemd is used on a read-only rootfs, /var must be a tmpfs. However, we may have packages that install stuff in there, and set important rights (via the permission-table). So, at build time, we need /var to be a symlink to the remanent location (/usr/share/factory) while at runtime we need /var to be a directory. One option would have been to have /var as a real directory even during build time, and in a target-finalize hook, move everything out of there and into the "factory" location. However, that's not possible because it's too early: some packages may want to set ownership and/or acces rights on directories or files in /var, and this is only done in the fakeroot script, which is called only later during the assembling of the filesystem images. Also, there would have been no way to undo the tweak (i.e. we need to restore the /var symlink so that subsequent builds continue to work) if it were done as a target-finalize hook. The only solution is to allow packages to register pre- and post-hooks that are called right before and right after the rootfs commands are executed, and inside in the fakeroot script. We can however not re-use the BR2_ROOTFS_POST_FAKEROOT_SCRIPT feature either because it is done before the filesystem command, but there is nothing that is done after. Also, we don't want to add to, and modify a user-supplied variable. So, we introduce two new variables that packages can set to add the commands they need to run to tweak the filesystem right at the last moment. Those hooks are not documented on-purpose; they are probably going to only ever be used by systemd. Signed-off-by: "Yann E.

Globally replace $(HOST_DIR)/usr/bin with $(HOST_DIR)/bin

2017-07-05T13:19:29+00:00

Since things are no longer installed in $(HOST_DIR)/usr, the callers should also not refer to it. This is a mechanical change with git grep -l '$(HOST_DIR)/usr/bin' | xargs sed -i 's%$(HOST_DIR)/usr/bin%$(HOST_DIR)/bin%g' Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

fs: set packages permissions even with no system device tables

2016-12-14T22:45:48+00:00

Currently, when there is no syztem device table (permissions or static devices) defined, then package permissions are not applied, because they are guarded by the check on the system device tables being non empty. Fix that by narrowing the guarding condition. Note that the dependency on host-makedevs was not conditional; we always build it even if we don't need it. Making it conditional is not possible, because we don't know all the packages permissions by the time the fs infra is parsed (packages from br2-external are parsed after it). Signed-off-by: "Yann E.

Revert "fs: use pseudo instead of fakeroot"

This reverts commit 8035ceb56cc3ba2541aba0d0ead3f29900d9e310. Moving to pseudo brought a number of issues (and longer compilation time), so lets stick with fakeroot now that the reported ubi issue has been worked around. Signed-off-by: Peter Korsgaard

fs: use pseudo instead of fakeroot

2016-11-03T20:36:15+00:00

fakeroot misbhaves when there are SElinux contexts, as reported in #9386, and further detailed in https://bugzilla.redhat.com/show_bug.cgi?id=1238802 A proposal in the FC bug is to use pseudo instead of fakeroot. Pseudo is a from-scratch re-implementation of fakeroot; it is used in Poky/OE instead of fakeroot. Fixes #9386. Reported-by: Andrey Yurovsky Signed-off-by: "Yann E.
