It is not at all nice. 1. it's incompatible ABI breakage 2. where will you put the key then, in the inode? :-) Changing to "SYSVID%d" is no good either. Look, people are ***parsing*** this stuff in /proc. The /proc filesystem is not some random sandbox to be playing in. Before you go messing with it, note that the device number also matters. (it's per-boot dynamic, but that's OK) That's how one knows that /SYSV00000000 is not just a regular file; sadly these didn't get a non-/ prefix. (and no you can't fix that now; it's way too late) Next time you feel like breaking an ABI, mind putting "LET'S BREAK AN ABI!" in the subject of your email? BTW, I suspect this kind of thing also breaks: a. fuser, lsof, and other resource usage display tools b. various obscure emulators (similar to valgrind) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
