Also, even if login.defs are not present, don't start allocating at 1, but at
SYSTEM_UID_MIN.
Fixes#9769.
The test is adjusted. Actually, it was busted before, because sysusers would
never use SYSTEM_GID_MIN, so if SYSTEM_GID_MIN was different than
SYSTEM_UID_MIN, the tests would fail. On all "normal" systems the two are
equal, so we didn't notice. Since sysusers now always uses the minimum of the
two, we only need to substitute one value.
We were looking at ${f%.*}, i.e. the $f with any suffix starting with a dot removed.
This worked fine for paths like /some/path/test-11.input. It also worked
for paths like /some/path/inline (there were no dots, so we got $f back unscathed).
But in the ubuntu CI the package is built in a temporary directory like
/tmp/autopkgtest-lxc.nnnfqb26/downtmp/build.UfW/ (yes, it has a dot, even two.).
That still worked for the first case, but in the second case we truncated things
after the first dot, and we would try to get
/tmp/autopkgtest-lxc.nnnfqb26/downtmp/build and try to load
/tmp/autopkgtest-lxc.nnnfqb26/downtmp/build.expected-password, which obviously
didn't work as expected. To avoid this issue, do the suffix removal only when
we know that there really is a suffix.
A second minor issue was that we would try to copy $1.expected-*, and sometimes
$1 would be given, and sometimes not. Effectively we were relying on there
not being any files matching .expected-*. There weren't any such files, but let's
avoid this ugliness and always pass $1.
All this test does is manipulate text files in a subdir specified with --testroot.
It can be a normal unittest without the overhead of creating a machine image.
As a bonus, also test the .standalone version.
