Upgrade przy pomocy sysupgrade powinien przebiegać bezproblemowo, natomiast upgrade systemu z okolic roku 2018 w roku 2024 dostarcza kilku problemów.

Problem 1 - setsy są w tar.xz

sysupgrade zainstalowany z pkgsrc z 2018 nie rozumie i nie rozpakowuje tego archiwum

Problem 2 - tar nie rozumie tar.xz

Tar z base systemy NetBSD 7.0 nie umie rozpakować archiwum tar.xz

Problem 3 - pkgsrc-2024q2 wpada w cyrkularną zależność przy próbie instalowania czegokolwiek, a że wszystko zależy od nowego pkg_install i mktools to w zasadzie nie da się nic zainstalować:

Rozwiązanie jakie wymyśliłem dające 100% sukcesu, jest następujące:

  1. Cofamy się do pkgsrc z okolic świetności systemu NetBSD 7.0 czyli np 2018Q3
cd /usr && cvs -q -z2 -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -r pkgsrc-2018Q3 -P pkgsrc
  1. Instalujemy GNU Tar
cd /usr/pkgsrc/archivers/gtar-base/
make install clean
  1. Pobieramy wszystkie a minimalnie base.tar.xz, comp.tar.xz, misc.tar.xz oraz modules.tar.xz z mirrora NetBSD. Może byc problem z certyfikatami SSL a także może być problem z brakiem narzędzia wget więc proponuję ftp i pobranie plików z lokalizacji: 
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-10.0/amd64/binary/sets/

Poniżej cały proces:

0:00
/0:58
  1. Następnie aktualizujemy tylko kernel oraz moduły przy pomocy gtar rozpakowując je do / i na koniec reboot
# gtar -zxvpf kern-XEN3_DOMU.tar.xz
./netbsd
# mv netbsd /
# gtar -zxvpf modules.tar.xz -C /
reboot
0:00
/1:24
  1. Mając działajacy kernel i moduły, możemy ręcznie rozpakować base system i pakiety pomocnicze. 
gtar -zxvpf base.tar.xz -C /
gtar -zxvpf comp.tar.xz  -C /
gtar -zxvpf misc.tar.xz  -C /
0:00
/1:12

To pozwala używać najnowszego pkgsrc (aktualnie 2024Q2), tak aby móc zaktualizować sysupgrade do najnowszej wersji, która umie obsłużyć archiwa tar.xz, a także zapewnia tar w base systemie współpracujacy z tar.xz i sysupgrade. Zatem kasujemy stare drzewo i pobieramy najnowsze:

# rm -rf /usr/pkgsrc
# cd /usr && cvs -q -z2 -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -r pkgsrc-2024Q2 -P pkgsrc
# cd /usr/pkgsrc/sysutils/sysupgrade

Trzeba jeszcze dodać do mk.conf - PKG_DBDIR=/var/db/pkg ponieważ zmieniło się domyślne miejsce instalacji paczek

  1. Wrzucamy/pobieramy wszystkie pliki do nowego katalogu z cachem od sysupgrade:
cd /root/10/
mv * var/cache/sysupgrade/
  1. Aktualizaujemy userland już przy pomocy sysupgrade:
sysupgrade sets
0:00
/1:30
  1. Następnie sprawdzamy, aktualizujemy i uzupełniamy pliki konfiguracyjne o zmiany miedzy 7.0 a 10.0 uważając aby nie nadpisać naszych ustawień.
sysupgrade etcupdate

Na koniec sprawdzamy czy są jakieś zalecenie do wykonania, które sprawdzenia nie poszły i uruchamiamy je:

sh /usr/sbin/postinstall -s /var/cache/sysupgrade/etc.tar.xz -s /var/cache/sysupgrade/xetc.tar.xz -d / fix opensslcertsrehash rc varshm obsolete

Jeżeli w polu postinstall checks failed: nie ma nic, upgrade wykonał się prawidłowo. Dla pewności można pościć sprawdzanie wszystkiego jeszcze raz przy pomocy:

sysupgrade postinstall
0:00
/1:13
  1. Należy wykonać reboot i system powinien wrócić jako już pełno prawny NetBSD 10.0, gdzie dalej można juz wykonać upgrade paczek z pkgsrc lub pkgin dla wersji 10.
