Help me with a research thingamajig. I want to find out who made Chroot. Wikipedia -- purely as a starting point -- shows a comment in the Chroot talk page stating, "This system call was present [in] AT&T versions of Unix well before 1982. This citation should be changed to point to an AT&T version. Indeed, Research's UNIX V7 sources (usr/sys/sys/sysent.c dated May 7th, 1979) has an entry at position 61 for chroot(2); the fact is even noted under the article about V7..." See: https://en.wikipedia.org/wiki/Talk%3AChroot#Bill_Joy_did_not_invent_chroot I know many of you are old-school Unix users/developers and some of you worked at AT&T. Who can help me find out which specific people (I need names) actually invented Chroot? ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan@vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
