Description Richard W.M. Jones 2019-12-10 15:52:21 UTC 
Description of problem:

Possibly related to or caused by the fix for bug 1770304?

On aarch64 only (and not other architectures) symlinks aren't
copied into the ext2 appliance correctly.  For example:

$ supermin -v -v -v --build /usr/lib64/guestfs/supermin.d -f ext2 -o /var/tmp/appliance.d

Examine /var/tmp/appliance.d/root, under /usr/lib64 inside the image:

$ guestfish --ro -a root -m /dev/sda
><fs> ll /lib64 | grep ssl
-rw-r--r--  1 root root      65 Nov 21 14:07 .libssl.so.1.1.1d.hmac
lrwxrwxrwx  1 root root      22 Dec 10 15:32 .libssl.so.1.1.hmac -> .libssl.so.1.1.1d.hmac
-rwxr-xr-x  1 root root  619400 Nov 21 14:06 libssl.so.1.1.1d

The file /usr/lib64/libssl.so.1.1 is missing.  However it is copied
in according to the supermin log.

Version-Release number of selected component (if applicable):

supermin-5.1.20-10.fc32.aarch64

Note for unknown reasons this only seems to affect aarch64, and
works fine on other architectures.

How reproducible:

100%

Steps to Reproduce:
1. See example above.
Comment 1 Richard W.M. Jones 2019-12-10 16:55:25 UTC 
This bug is very strange.

This command fails:

$ supermin --prepare `cat /usr/lib64/guestfs/supermin.d/packages` -o /var/tmp/supermin.d
$ supermin --build /var/tmp/supermin.d -f ext2 -o /var/tmp/appliance.d

This command works:

$ supermin --prepare `grep -v policycoreutils /usr/lib64/guestfs/supermin.d/packages` -o /var/tmp/supermin.d
$ supermin --build /var/tmp/supermin.d -f ext2 -o /var/tmp/appliance.d

The difference is the inclusion of policycoreutils in the package list.  However
I see nothing wrong in policycoreutils.

Comment 4 Richard W.M. Jones 2019-12-10 17:13:15 UTC 
policycoreutils pulls in a notably large number of extra packages, it does
make me wonder why we need it at all.  Anyway it could be one of these
dependencies which is causing the problem, but I cannot see any
immediate problems in any of them.
