            Bug ID: 291043
           Summary: etcupdate fails to build tree since fork of stable/15
           Product: Base System
           Version: 15.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

etcupdate failed extracting new tree

etcupdate fails to build new tree if FreeBSD is installed from scratch, then
/usr/src compiled using commands:

1. remove /usr/src, /usr/obj: rm -rf /usr/src /usr/obj; mkdir /usr/src /usr/obj
2. pull new sources: git clone https://github.com/freebsd/freebsd-src.git
/usr/src
3. checkout stable/15: git checkout stable/15
4. cd /usr/src/sys/amd64/conf; ln -s /root/kernel/FBSD15 .

Now sources are ready to compile:
5. make buildworld KERNCONF=FBSD15
6. make buildkernel KERNCONF=FBSD15
7. make installkernel KERNCONF=FBSD15

8. Now remove etcupdate db: rm -rf /var/db/etcupdate; mkdir /var/db/etcupdate
We'll start with a blank etcupdate db.
9. etcupdate extract

This fails with "Failed to build new tree".
Nothing is created in /var/db/etcupdate, except "log" (attached).

If you instead do:
1. remove /usr/src, /usr/obj: rm -rf /usr/src /usr/obj; mkdir /usr/src /usr/obj
2. pull new sources: git clone https://github.com/freebsd/freebsd-src.git
/usr/src
3. checkout stable/14: git checkout stable/14
4. cd /usr/src/sys/amd64/conf; ln -s /root/kernel/FBSD14 .
5. make buildworld KERNCONF=FBSD14
6. make buildkernel KERNCONF=FBSD14
7. make installkernel KERNCONF=FBSD14
8. rm -rf /var/db/etcupdate; mkdir /var/db/etcupdate
9. etcupdate extract

Will work as expected.


"etcupdate extract" works for:
- stable/13
- stable/14

"etcupdate extract" fails to write new tree for:
- stable/15
- current

All systems tested are "root on zfs" with settings as advised by chapter 2.5 -
Using bsdinstall. Systems are set up by bsdinstall with:

# mount
zroot on / (zfs, local, nfsv4acls)
devfs on /dev (devfs)
zroot/home on /home (zfs, local, nosuid, nfsv4acls)
zroot/home/sct-muc on /home/sct-muc (zfs, local, nosuid, nfsv4acls)
zroot/tmp on /tmp (zfs, local, nosuid, nfsv4acls)
zroot/usr on /usr (zfs, local, nfsv4acls)
zroot/usr/ports on /usr/ports (zfs, local, nosuid, nfsv4acls)
zroot/usr/ports/distfiles on /usr/ports/distfiles (zfs, local, noexec, nosuid,
nfsv4acls)
zroot/usr/ports/packages on /usr/ports/packages (zfs, local, noexec, nosuid,
nfsv4acls)
zroot/usr/src on /usr/src (zfs, local, noexec, nosuid, nfsv4acls)
zroot/var on /var (zfs, local, nfsv4acls)
zroot/var/crash on /var/crash (zfs, local, noexec, nosuid, nfsv4acls)
zroot/var/db on /var/db (zfs, local, noexec, nosuid, nfsv4acls)
zroot/var/db/pkg on /var/db/pkg (zfs, local, nosuid, nfsv4acls)
zroot/var/empty on /var/empty (zfs, local, noexec, nosuid, read-only,
nfsv4acls)
zroot/var/log on /var/log (zfs, local, noexec, nosuid, nfsv4acls)
zroot/var/mail on /var/mail (zfs, local, noexec, nosuid, nfsv4acls)
zroot/var/run on /var/run (zfs, local, noexec, nosuid, nfsv4acls)
zroot/var/tmp on /var/tmp (zfs, local, nosuid, nfsv4acls)
procfs on /proc (procfs, local)
linprocfs on /usr/compat/linux/proc (linprocfs, local)
fdescfs on /dev/fd (fdescfs)

Setup is the same for FreeBSD 13, 14, 15 and CURRENT.


If you already have an etcupdate database, etcupdate works as expected for all
systems: FreeBSD 13, 14, 15 and CURRENT.
It is only "etcupdate extract" witch fails!

Comparing "etcupdate" from FreeBSD 14 with "etcupdate" from FreeBSD 15 there is
no difference, except with FreeBSD 14 "mergemaster" is available, while it is
not with FreeBSD 15.

If "etcupdate" fails within log you'll find:
