+xbps-src:
+ * Personalized scripts per template to unpack distfiles.
+ * Multiple URLs to download source distribution files, aliases, etc.
+   Something like ${sourceforge} to pick up any specified mirror on the list.
+ * Fix -C flag while building packages via chroot.
+
+Packages:
+ * Create /etc/issue.
+ * Add a trigger for fc-cache.
+ * Add a trigger to (un)register users/groups. Currently packages that
+   require user/groups use custom INSTALL/REMOVE scripts, which adds
+   a lot of duplicated work.
+ * Add support to stop and restart package's OpenRC service while
+   removing and upgrading a package.
+   [PARTIAL: at pre-remove the services are stopped but not yet restarted]
+ * How to handle kernel package upgrades? dpkg seems to keep previous
+   package and its initramfs, and a dummy package depends on the latest one.
+   I think this is the best option.
+ * Fix initramfs-tools trigger for $pkgname != kernel.
+ * Fix initramfs-tools 'update-initramfs -a'.
+ * Fix HAL/PolicyKit for nonroot to be able to admin tasks.
+ * Fix loadkeys(1) incorrectly loading the olpc keymap vs qwerty.
+
+xbps-bin:
+ * Add support to install binary packages without any repository.
+ * Add a flag to reinstall a package version that is already installed,
+   overwritting files on disk and updating required_by if required.
+   Perhaps change the automatic-install object to false, like pkg_install
+   from NetBSD do.
+ * Implement shell style match patterns with fnmatch() for install, update
+   and remove.
+ * Make -f flag to overwrite files when installing, and to ignore
+   files with wrong checksum or unexistent when removing.
+   [PARTIAL: only unexistent files are ignored when removing]
+
+libxbps:
+ * Add support to upgrade packages but overwritting current files;
+   this will fix libc, sh and others. An "essential" boolean obj
+   seems to be a good way to find such packages, like dpkg.
+   [PARTIAL: files are overwritten but obsolete files are not
+    taken into account yet]
+
+xbps-repo:
+ * Add support to add only specified packages, rather than looking
+   at all files in a directory.
+ * Add support for remote repositories, requires libfetch.
