this file lists +pros and -cons for the translucency linux kernel module +works for recent linux kernel v2.4 (2.4.3-2.4.22 tested) -compatibility for v2.2 has been lost (see old/transhack4.c for thus) +transparent to user-space-processes +no recompiling of statically linked binaries etc +transparent to the kernel - thus all fs and medii should work -has to be recompiled for every kernel and for every update ?-only for i386+alpha yet (segmentation issues) ?is this still true? Who tried? -harder to debug -can crash the machine -needs more security-checks +management and info per /proc/sys/translucency/* +allows as many redirections and as many overlay-layers as you want +creates dirs and devices when needed +copies files on the fly -sometimes too many ("touch file" must copy it) -wastes some space since it is no versioning system +does not try to copy devices/fifos/sockets or /proc/something -symlinks are followed, but not yet redirected properly ?+avoids directory loops (implicitly) ? +merges directory listings +does not need special index or container files +thus fast -may break POSIX compliance -can sometimes put files in wrong dir when upper layer is_subdir of lower layer or other way round (bug)
