The libraries in the 'clibs' package must be installed before the rest of the system can be safely upgraded, to ensure consistency with the core runtime libraries. > Misspeling FreeBSD-debug, FreeBSD-development and FreeBSD-profile as > FreeBSD-runtime-debug, FreeBSD-runtime-development and FreeBSD-runtime-pr= ofile? >=20 I am not sure why this was originally named as they are, but this can be fixed. > I am reseach spliting to package and try some aggregation: >=20 > NumPkgs tarSize(MB) flatSize(MB) Aggregation > 1 30.7 102 FreeBSD-kernel-generic-release > 1 57.1 331 FreeBSD-kernel-generic-debug > 1 2.8 5.4 FreeBSD-clibs > 1 3.5 24 FreeBSD-clibs-development > 1 2.4 11 FreeBSD-clibs-debug > 1 1.3 9.8 FreeBSD-clibs-profile > 1 20.7 103 FreeBSD-runtime > 1 5.9 38.1 FreeBSD-development > 1 2.9 2.8 FreeBSD-runtime-manuals > 1 14.9 65 FreeBSD-debug > 1 2.2 12.5 FreeBSD-profile > 1 24.3 93 FreeBSD-clang > 1 8.7 66 FreeBSD-clang-debug > 116 19.0 80 FreeBSD-* > 89 3.2 14 FreeBSD-*-development > 110 12.5 61 FreeBSD-*-debug > 85 2.8 13 FreeBSD-*-profile > 85 6.0 18 FreeBSD-*-lib32-* > 88 7.4 30 FreeBSD-*-lib32-development > 84 11.6 43 FreeBSD-*-lib32-debug > 85 5.8 24 FreeBSD-*-lib32-profile >=20 > I.e -development is substantially less of main package and don't need > separatly (and many .so incorrectly packaging into -development). > Same as -profile vs -debug (and -profile useless w/o -debug). >=20 Regarding the .so files, I am not clear on the original intent behind separating the actual shared library from the installed symbolic link to the real shared library, but in my investigation into this, only the symlinks are provided by the '-development' package. For example: root@pkgbase:/ # file /usr/lib/libjail.so /usr/lib/libjail.so: symbolic link to ../../lib/libjail.so.1 root@pkgbase:/ # pkg shlib libjail.so No packages provide libjail.so. No packages require libjail.so. root@pkgbase:/ # pkg shlib libjail.so.1 libjail.so.1 is provided by the following packages: FreeBSD-jail-11.0.s20160303044402 FreeBSD-jail-lib32-11.0.s20160303044402 libjail.so.1 is linked to by the following packages: FreeBSD-runtime-11.0.s20160303044402 Moving them to the package that installs the shared library itself should be fairly easy to do. Regarding '-profile' and '-debug' package separation, it is possible to install the debugging files without requiring the profiling libraries now, so I think keeping them as separate packages is the best way to achieve this. (Note, profiling libraries will not be installed with WITHOUT_PROFILE=3D1 in src.conf(5)). > Manual must be installed always, IMHO (size is small and version of > manual must matcj version of utility). >=20 This is similarly broken up by package, at least where it has been found so far. The jail.conf(5) manual is only installed if the 'FreeBSD-jail' package is installed, for example. root@pkgbase:/ # pkg which /usr/share/man/man5/jail.conf.5.gz /usr/share/man/man5/jail.conf.5.gz was installed by package FreeBSD-jail-11.0.s20160303044402 > Packaging of individual utilites is useless (total 19MB vs > 30.7+2.8+20.7+2.9) and incorrect (for example, WITHOUT_ACCT not only > don't build accton/lastcomm/sa but also cut off accaunting code from > kernel for space saving and perforamce). >=20 Packaging individual utilities is not useless, depending on who you ask. One of the first replies I received when starting separating userland utilities into separate packages was further splitting rwho(1) and rwhod(8) into different packages, the use case being not necessarily needing (or wanting) the rwho(1) utility on systems where rwhod(8) runs. > I am propose don't distinct profile and debug, development and main > package. >=20 > I am propose divide only to FreeBSD-kernel, FreeBSD-clibs (clibs, > runtime and manuals), FreeBSD-clang, FreeBSD-lib32. >=20 This will make updates for SAs and ENs too large. This is part of the reason the packages were split up as they have been so far (and will continue to be further split as progress is made). If the argument is simply "there are too many packages", see one of the previous replies in this thread that discusses the background on why this decision was made. But that aside, trying to make everyone happy will turn out to make no one happy. > Dividing to many packages is anoyning on install and maintancing (what > exact keys of this utilites this version?! stupid admin don't install > manuals!) >=20 > About use cases.

The PKG_VERSION evaluates the BRANCH =66rom Makefile.inc1 to determine if it should use the timestamp. (Since -CURRENT is a fast-moving target, and we recommend keeping the userland and kernel in sync, this makes sense, at least to me.) > 2. After src.conf change some package don't build.

But otherwise, the generated packages respect make.conf(5) and src.conf(5), so this should not happen in theory. > 4. How install debug symbols after installing separately set of > packages?

This will also be required for architectures we do not have an upstream package repository (powerpc, for example). This is handled by the 'package-pkg' target at the moment. > As for windows (please found in garbage CD with exact version and > insert in lost CD-ROM)? >=20 > May be preserve for this all packages in some places on HDD? >=20 I am having trouble parsing these two sentences. Could you please clarify? > 6. pkg which /etc/ssh/ssh_config > /etc/ssh/ssh_config was not found in the database >=20 There are may occurrences of this at the moment. Configuration file merging needs to be resolved in pkg(8) before we can safely add files like sshd_config(8) to the 'FreeBSD-ssh' package. > What?! How to handle this? What is instead of mergemaster? > (etcupdate currently to dangerous, I am totaly destroed one host by > etcupdate. Also, current database of etcupdate is very strange). We use etcupdate(8) in the FreeBSD infrastructure, and have not run into such problems.
