  • Description of the issue (ideally so that others can reproduce it):
    the running system have the following network config:
ip -br a
lo               UNKNOWN        127.0.0.1/8 ::1/128
eth0             UP             10.XX.XX.50/27 fe80::XXX:XXXX:fe01:9a79/64
eth1             UP             2a01:XXX:XXXX:XXXX::55/64 fe80::XXX:XXXX:fe01:9a7a/64

so IPv6 on the eth1.

mkrescue runs normally:

TMPDIR=/tmp /usr/sbin/rear mkrescue; echo $?
Failed to copy all contents of /lib/modules/5.14.0-474.el9.x86_64 (dangling symlinks could be a reason)
/usr/lib64/systemd/libsystemd-core-252.so requires additional libraries
        libsystemd-shared-252.so => not found
ReaR recovery system in '/tmp/rear.vO06Zi3IVKjl8Hf/rootfs' needs additional libraries, check /var/log/rear/rear-SERVER.log for details
0

Then after booting into the ReaR the interface eth1 has no IP. This is a big issue because eth1 is our backup interface :(

I do not have any protocol of what the "ip a" output looks exactly, but I just want to open this issue to ask if the bug is already known and there is already a known fix for this?

@damm620 PR #2907 fixed this and will be part of ReaR v3.0 once it gets released.
When will it be released? The answer you can find in https://relax-and-recover.org/events/ - "Why is there no new Release? Nobody pays for the basics :-("
