Niltze, Ed-
I am experiencing segfault when using dpkg (package manager for
debian) utility to unpack software.
It happens *both* during reiser4 sfrn 5.1.3 -enabled Debian Installer
(d-i) *and* in a pure sfrn 5.1.3 Debian Buster environment,
i.e., formatted in sfrn 5.1.3 and running reiser4progs 2.0.0 and
corresponding kernel. It happens in VirtualBox 6.1.4
Do you have any bootable image I could download and reproduce that oops
on my virtual machine?
Ah, I see a mistake, which most likely causes that oops.
Will provide a fixup soon..
as well as in actual
physical hardware, same BUG line.
This BUG makes it impossible to carry out a native Debian Buster
installation onto a default reiser4 SFRN 5.1.3 -formatted
partition, i.e., reg42, with or without specifying a stripe, i.e., -t
256K. Accordingly, even if a user uses cp -a back-and-forth
to hack a pure SFRN5 Debian system whenever a software upgrade occurs
a segmentation fault will follow.
Unaware if other package managers, like RPM/YUM utilities, etc., will
cause a segfault as well.
