Solved /usr/lib disk usage differences between 11.2 and 12.0

Are these differences in disk usage normal?

FreeBSD 11.2-RELEASE:

Code: 
du -sh /usr/lib
475MB

du -sh /usr/lib/debug/usr/bin
166MB

FreeBSD 12.0-RELEASE:
Code: 
du -sh /usr/lib
1.2G

du -sh /usr/lib/debug/usr/bin
547MB
 
I suspect you have a bunch of old libraries lingering in /usr/lib. Is the 12.0-RELEASE an upgrade? If it is, how did you upgrade?

Code: 
dice@maelcum:~ % du -sh /usr/lib
552M    /usr/lib
dice@maelcum:~ % uname -a
FreeBSD maelcum.dicelan.home 12.0-STABLE FreeBSD 12.0-STABLE r343956 MAELCUM  amd64
 
Yes it's an upgrade from 11.2.

Code: 
svnup release

cd /usr/src

make buildworld
make buildkernel

make installkernel
mergemaster -p
make installworld
mergemaster -Ui

make -DBATCH_DELETE_OLD_FILES delete-old
make -DBATCH_DELETE_OLD_FILES delete-old-libs
 
FreeBSD 11.2:

Code: 
root@server:/usr/lib/debug/usr/bin # du -sh * | grep M | sort
 14M    clang.debug
 46M    ld.lld.debug
 50M    llvm-tblgen.debug
1.0M    openssl.debug
1.1M    svnlite.debug
1.2M    as.debug
1.2M    troff.debug
1.9M    nvi.debug
7.3M    llvm-objdump.debug
8.0M    lldb.debug
9.3M    clang-tblgen.debug

FreeBSD 12.0:

Code: 
root@server:/usr/lib/debug/usr/bin # du -sh * | grep M | sort
 11M    llvm-cov.debug
 11M    svnlite.debug
 17M    llvm-objdump.debug
 84M    ld.lld.debug
1.9M    nvi.debug
135M    lldb.debug
166M    clang.debug
3.3M    make.debug
3.4M    objdump.debug
3.7M    svnliteversion.debug
3.8M    clang-tblgen.debug
4.1M    dtc.debug
4.7M    svnlitefsfs.debug
5.0M    svnlitedumpfilter.debug
5.0M    svnlitelook.debug
5.1M    svnliteadmin.debug
5.4M    ar.debug
5.6M    svnliteserve.debug
5.9M    ld.bfd.debug
6.1M    as.debug
6.8M    svnlitesync.debug
7.7M    llvm-tblgen.debug
8.6M    svnlitemucc.debug
8.7M    svnlitebench.debug
8.8M    svnliterdump.debug
 
I don't think that something left from 11.2

For example ld.lld.debug has big difference between 11.2 and 12.0.

And everything inside /usr/lib has new date.
 
Code: 
$ du -sh /usr/lib
86M    /usr/lib

$ du -sh /usr/lib/debug/usr/bin
du: /usr/lib/debug/usr/bin: No such file or directory

I use the GENERIC kernel without /etc/src.conf in both cases.

Also I think DEBUG option in GENERIC kernel is enabled by default in 11.2 and 12.0.

What I try to find is if the disk usage is normal or something is not good with my system.
 
If you're using a -RELEASE version with a GENERIC kernel, why don't you update using freebsd-update(8)?

Does /etc/make.conf exist? If so, what does it contain?
 
I find it easier to upgrade using source.


cat /etc/make.conf

DISABLE_VULNERABILITIES=yes
SSHGUARDFW=ipfw
OPTIONS_UNSET=X11
WITH_PKGNG=yes
DEFAULT_VERSIONS+=ssl=openssl
DEFAULT_VERSIONS+=php=72
DEFAULT_VERSIONS+=bdb=6
 
Remove the DISABLE_VULNERABILITIES, the SSHGUARDFW is pointless and WITH_PKGNG is useless too. But none of them have anything to do with the system's libraries so that's not a cause of this issue. The DEFAULT_VERSIONS seem to be fine but those are only for ports and have no influence on the base OS.
 
Can you run this command in your system?

Code: 
du -sh /usr/lib/debug/usr/bin/clang.debug

166M    /usr/lib/debug/usr/bin/clang.debug
 
Code: 
dice@maelcum:~ % du -sh /usr/lib/debug/usr/bin/clang.debug
 73M    /usr/lib/debug/usr/bin/clang.debug
 
Oh, wait. I suddenly realized something. 12-STABLE recently got a major update for Clang, LLVM, etc. That might explain at least some of the differences.

Double checking a 12.0-RELEASE:
Code: 
dice@case:~ % uname 
FreeBSD case.dicelan.home 12.0-RELEASE-p3 FreeBSD 12.0-RELEASE-p3 GENERIC  amd64
dice@case:~ % du -sh /usr/lib
180M    /usr/lib
Still, nowhere near the 1.2GB you appear to have.
 
I'm afraid I can't explain either why the difference is that big on your machine. However, if the size is a problem for you, just set WITHOUT_DEBUG_FILES=yes in /etc/src.conf, as already mentioned. You don't need the debug files if you're not a developer and/or if you don't need to hunt down bugs.
See the entry labeled “20151207” in /usr/src/UPDATING, and the src.conf(5) manual page.

It does not matter at all which packages you install, because those go into /usr/local, while /usr/lib belongs to the base system.
Also see the hier(7) manual page for reference; it describes in detail the layout of FreeBSD's file system hierarchy.
 
Hmm my /usr/lib is 1.9 GB big, of which 1.5 GB /usr/lib/debug. Guess make delete-old-libs doesn't do what I thought.
