/ is no longer Reiser4 :(
Following Han's comment about the deliterious effects of 6% fragmentation, I attempted a manual defrag of my hard disk. While restoring the .tar file, I had nothing better to do than watch it. And a good thing too! It got a recurring oops. about every other minute or so, it would stop with a long kernel message than mostly scrolled off of the screen... I thought those where supposed to show up in a log files somewhere if possible, but I can't find it. And it should have been possible, as the computer continued to run just fine. These oopses caused some sort of data corruption - root wouldn't boot properly afterwards. So I reformated as ext3 and untarred my root again. That worked fine, so I know it wasn't corruption of the tar file. I took a photograph, and I'll try to type in some of it. Just looking at the names of the procudures, it looks like memory pressure made reiser4 flush, and then some of the lower level functions tried to allocate memory and failed. But since I don't have the top of the oops message, I can't tell. Wait - I could've stopped the scrolling with ^S, scrolled back with ^pageup, and photoed the whole thing! Aaaargghh Well, I'm not redoing it right now, I need to be getting to bed. I may try it again later - but then maybe I'll update to 2.6.14-mm2 with patch from namesys first... Here's the (tail end of the) oops message, sans addresses and offsets because I'm feeling lazy and I'm in a hurry: mempool_alloc+0x3a/0xe0 __split_bio+0x128/0x190 in_drive_list dm_request generic_make_request submit_bio do_IRQ reiser4_clear_page_dirty write_jnodes_to_disk_extent write_jnode_list write_fq flush_current_atom flush_some_atom writeout reiser4_sync_inodes writeback_inodes background_writeout pdflush __pdflush pdflush background_writeout kthread kthread kernel_thread_helper
Re: need opinions from sysadmins on where reiser4progs should install

If I wanted /, I'd have specified that on configure time. If it installed in / by default, it would, often, hit the sacred package-system managed area of the VFS tree annoying people like me to a very great extend, so please don't. pgptWAWCAb7TX.pgp Description: PGP signature
Re: File as a directory - file-as-dir vs. link-dirs (again) - 3/3

Yes, my relational model *does* uses standard directories, with three differences. 1) foofs's internal implementation of link-directories and other directories might be different. Or it might not. Entirely unimportant at this level. 2) gc might treat some link-directories differently to predicate-directories.
