Update kernel with not enough HD space available 2. Reboot Actual Results: System tries to boot new kernel although initrd missing Expected Results: RPM should notice that mkinitrd failed. Then, bootloader should not be updated and package installation should fail. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Unfortunately, 4) leaves the corrupted initrd lying around instead of removing it, but exits with 8, which 3) uses as an exit code as well, signaling an error. 2) does not check the exit code so installation of the RPM succeeds. 1) checks for the existance of an initrd file and finds the corrupted one, then adds the new kernel as default to the bootloader. => Voila, system does not boot :) Another note: inside the RPM prescript, there is a check if more than 20MB of free space is available on the device before installation. As the initrd of OS12.3 is rather large (see bnc #801883), this value should probably be raised to 40+ MB at least, which would be a (not really nice) workaround. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
