As first post on this subject (but with a bogus subject line) started with: "I need to have two copies of CygWin running. Really I do!", the use of chroot never came to my mind, but you're right: one $ chroot /full/path/to/new/tree should do it :)
He'll have to make sure Cygwin1.dll is always found in the PATH, though. This renders it impossible from the Bash command-line, because PATH is mangled at start-up (of Bash), but from cmd, there is no problem (I just tried). If this isn't what he's trying to do, I'm sure he'll get back to the list with his forking experiments :) rlc On Tue, 18 Feb 2003, John Vincent wrote: > Hi there, > > I may be missing something, but from you're original email > it looks to me like you don't need another cygwin1.dll at all! > > I think all you need is a script with a few calls to umount and > mount to fix your file mount points and a call to chroot to change > the file system root, plus some changes to the PATH environment > variable. > > Try "man chroot", "man umount" and "man mount" to see how these > commands work.
