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 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. Mar 8 20:20:19 debootstrap: Selecting previously unselected package base-passwd.
