I'm looking for some general information regarding fast file systems ( using contiguous or consecutive sectors on a hard disk ) and modifications to the kernel that allow a process to change it's priority level. Are there any standards for these items? ( AT&T SVID ) Have any manufacturers implemented these features? How have they implemented them? ( system calls, any libraries? ) Do you like the way they did it? Any other comments! Please e-mail and I will summarize if enough response. Thanks in advance, necis!geo -- necis!geo "Just a Saint of Circumstance, just a tiger in a trance."

Dunno 'bout fast file systems, but I agree it sure would be nice (pun intended) if a non-setuid process had a way to modulate its priority (both upward and downward) within the constraint of what it was granted at invocation. (Setuid root processes can nice() themselves up and down at will, but I presume the emphasis is on user code? Or maybe it is acceptable to be setuid root in a dedicated applications environment [not a general purpose user environ- ment]?) -- ------------------------------- Disclaimer: The views contained herein are | dan levy | yvel nad | my own and are not at all those of my em- | an engihacker @ | ployer or the administrator of any computer | at&t computer systems division | upon which I may hack. | skokie, illinois | -------------------------------- Path: ..!{akgua,homxb,ihnp4,ltuxa,mvuxa, vax135}!ttrdc!levy
