I have all of my machines sharing some local binaries and docs, but the files are typically small and the network is gigE, so I doubt it will hurt me. On the other hand I do know people running workstations with virtually everything NFS mounted, working with large image files. The initial bug report makes it look as if it's about two orders of magnitude slower, but doesn't quantify the effect on more common sequential access operations. If this becomes an issue in 2.6.17, I hope it will show up in -stable before 2.6.18, the current development cycle is a bit, um, protracted... lately. -- Bill Davidsen Obscure bug of 2004: BASH BUFFER OVERFLOW - if bash is being run by a normal user and is setuid root, with the "vi" line edit mode selected, and the character set is "big5," an off-by-one errors occurs during wildcard (glob) expansion.
