The idea was to add the login user automatically in the Hurd postinst file,
but adduser did not support negative uids. Now it does, but I forgot about
changing the postinst file. Anyway, if we were to specify -1 as the uid
now, we still have the problem that putpwent in glibc has this code:
if (fprintf (stream, "%s:%s:%lu:%lu:%s:%s:%s\n",
p->pw_name, _S (p->pw_passwd),
(unsigned long int) p->pw_uid, (unsigned long int) p->pw_gid,
_S (p->pw_gecos), _S (p->pw_dir), _S (p->pw_shell)) < 0)
Note the (unsigned long int) p->pw_uid. So the uid will come out as
ULONG_MAX or so in the passwd file. Is this safe?
The other possibility is to include the login user in the passwd/group master
file in base-passwd. This is Architecture: any, so that's okay (I think it
was architecture all before, and we ruled it out because of this).
This is the more correct fix anyway, as the value must never change. I
will file a bug report about it.
We also need an entry for -1 in the group file, right?
Thanks,
Marcus
