Bug#452081: makedb broken on alpha/sid

[Peter Palfrader <weasel@debian.org>]

Package: libc6.1
Version: 2.6.1-6
Severity: important

Hi,

In the sid chroot of albeniz.debian.org, an alpha machine, makedb cannot
build the passwd database:

albeniz:~# strace -f chroot  /srv/albeniz.debian.org/chroot/sid makedb /var/lib/misc/albeniz.debian.org/passwd.tdb -o /var/lib/misc/passwd.db.t

it appears the db_open fails for some reason or other.

The same command works without problems in the lenny chroot.  With the
same libdb4.3, with the same libnss-db (which is the package that has
makedb).  Downgrading the libc in sid to the one in lenny (2.6.1-6 ->
2.6.1-1) makes makedb work.


Since albeniz is our alpha porter box you should have accounts on it,
and it's no problem to reproduce it as a user:

[sid] @albeniz:~$ rm -f __db.test test
[sid] @albeniz:~$ makedb /var/lib/misc/albeniz.debian.org/passwd.tdb -o test
makedb: cannot open output file `test': Function not implemented

(no, nss won't know your name in the sid chroot until this bug's fixed :)
