fakeroot

fakeroot copied to clipboard

fakeroot can be built to either use SYSV IPC or TCP for message passing.

Cases for which the SYSV IPC version fails or causes problems but for which fakeroot-tcp has been observed to work well include the items listed below.

• Multithreaded applications (using pthread)
• Running under realtime-preempt kernel

Portability Notes

On OS X, only binaries that do NOT rely on Mach-based [e]uid/[e]gid/mode APIs will correctly use fakeroot altered ownership/permissions. See README_MACOSX.txt for further information.
