Add a cleanup command and DBus API We sometimes talk about using `ostree admin undeploy`, but that doesn't know about the pkgcache, and hence space there leaks until the next rpm-ostree operation. Just for this, we need to expose a cleanup command (and API). But we also need to support cleaning: - repomd - downloads (repo/tmp) So let's start implementing that. Closes: #614 Approved by: jlebon

Introduce "treespec" concept as GKeyFile I debated config file formats a lot. JSON is fairly awkward for humans to write, and really painful to parse from C. YAML is nice, but also painful from C. Both are fairly overpowered for what we really need. Keyfiles (desktop spec, `GKeyFile`) have a lot of limitations, but at least it's used by systemd and `.desktop` files, and we already have a parser. We still parse the JSON treefiles, but internally convert them to `GKeyFile` (which is in turn converted to `GVariant` for a canonical form).

core: Make unprivileged case ignore ownership, add "_compose" context I was in the process of trying to support `%post` scripts, and I wanted to use `rpm-ostree container` for convenient and safe testing. However the recent package layering changes broke it to error out on perms like `filesystem`'s `root:mail` on `/var/mail`. I decided to introduce a new `rpmostree_context_new_compose` which had the current behavior, switch `compose tree` to use it, and then change `_new_unprivileged` to *really* be unprivileged. Specifically we ignore file ownership (and fix dir owners) because we assume we'll be operating with `bare-user` repos. Closes: #327 Approved by: jlebon

compose: Introduce variable substitution for ${basearch} This comes from the tradition of yum repo files. It's significantly easier for rpm-ostree users building multiple architectures if some core templating for the treefiles is built in. Otherwise, everyone needs to learn about a new wrapper tool for rpm-ostree, and said tool would need to re-do the same "basearch" evaluation that is already occuring inside libhif. This commit also paves the way for introducing `${releasever}` substitution. NOTE: This depends on pending changes to libhif git. Closes: #274 Approved by: jlebon

Support "system/regenerate-initramfs=true" flag in origin Currently we push for a model where the initramfs is generated (in non-hostonly mode), and merely replicated. However, to support a few unfortunate corner cases like dm-multipath which wants to inject a config file into the initramfs, we need to support regenerating it client side too. Down the line, we'll need this to support overriding the kernel too. This changes things in the core to add the concept of an "empty" `RpmOstreeContext`. I initially tried skipping it, but that was too much duplication. We still want all of the core ostree-related logic that lives in that code too. The treespec bits barfed if the spec didn't have a `tree/packages` key. It was simplest to change that to allow it - and because that was the only case where we errored out in parsing, I dropped the error handling. There was another place in the upgrader that now needed to be fixed to handle transitioning from just regenerating initramfs to not. Closes: #574 Approved by: jlebon

pkglayering: Commit in base repo, not pkgcache Currently, we do the final commit into the pkgcache repo, then pull it to the base. The problem with this is that, combined with the fact that we're not presently pruning the pkgcache repo, we leak space. In preparation for a cleaner fix for this, rework things so that the core infra can know about *both* a base repo and a pkgcache repo. If they're separate (as is the case for rpm-ostree-on-host), whenever we are doing layering, explicitly pull just the `.file` objects that are referenced into the parent repo. We do the final commit in the base repo. Closes: #437 Approved by: jlebon

passwd_prepare_rpm_layering: account for local entries On Fedora 25, systemd adds a sysuser config file for multiple users. It also explicitly creates those same users in its %pre, except for one: systemd-coredump. This means that the tree's /usr/lib/passwd doesn't contain systemd-coredump. Of course, on first boot, it gets created and added to /etc/passwd. During package layering, we map /usr/lib/passwd to the container's /etc/passwd. If the %pre calls useradd/groupadd without passing an explicit uid/gid, it's possible that the allocated id is already in use by an entry in the deployment's /etc/{passwd,group} (such as systemd-coredump, but the same holds for any manually-added entry). We resolve this by taking the switcheroo a step further: we map /usr/lib/passwd to /usr/etc/passwd, and then also map /etc/passwd to /usr/lib/passwd. That way, useradd in %pre will account for already allocated local uids and react accordingly. Closes: #561 Approved by: cgwalters

core: Initial implementation of %posttrans using bwrap+rofiles-fuse In order to make many things work, we need to run scripts. Short version: For now, we: - Run `%posttrans` - Treat most `%post` as the same as `%posttrans` - Ignore `%preun` and such since we never uninstall Most importantly though, we start to build up an "override" list for script handling. Currently it's just a blacklist of scripts we don't need. Significant work here would be needed to run Lua scripts, so far I've been able to just skip them. Closes: #338 Approved by: jlebon

Since here we will be using the sysroot repo, we need the ability to set the repo. Just add a new set function for now, maybe move it into new_system() later. Also, make sure we dereference the repo on finalize. Pull request: #240 Approved by: cgwalters

Add --noscripts concept for pkg-add/delete Right now, while one can `pkg-add strace`, there are a lot of packages with `%post`. Since some current developers want to use package layering as it is today, let's add the concept. Even after we have a whitelist of scripts and have cleaned up Fedora to use them, we'll still have potential issues with 3rd party RPMs etc. for a long time, so allow people this out to stumble forward for those and potentially run them by hand if necessary.
